Abstract: This study was carried out to investigate effect of Pomegranates juice (PJ) on the testis of aged male albino rat. PJ is a strong antioxidant used for many medical disorders. Animals were randomly divided into 3 groups of ten rats for control group and fifteen rats for each other two groups. In (group I) and (group II) animals were received distilled water by gavage daily for 52 days. Where in (group III) animals were received PJ by gavage at a dose of 10 ml/kg/day daily for 52 days. All animals were sacrificed at the end and testis were separated and processed. Light microscopic studies of aged animals demonstrated loss and degeneration of germ cells, sertoli and leyding cells. Excessive collagen deposition in aged group was detected. Morphometric studies exhibited decreased epithelium height, diameter of STs in aged group. While biochemical studies showed decreased testosterone level and increased FSH& LH. PJ group showed improved pictures nearly similar to control group. Therefore, it is noticed the beneficial effect of pomegranate juice on testis in aged rats that may makes it one of the most important foods for the future.

Abstract: Sepsis is frequently the cause of severe pulmonary dysfunction. Gentamicin is used clinically due to its wide spectrum of activities against infections; however it has serious adverse effects and life-threatening toxicity. The challenge for scientists is to develop alternative therapy or protective agents against its toxicity. Hence the present study is an attempt to elucidate the possible protective role of virgin olive oil with or without gentamicin against the toxic changes on the lung induced by sepsis. Thirty six adult male albino rats were used and divided into three groups. Group I: served as the control group, Group II: lung sepsis was induced by intraperitoneal injection of E. coli LPS serotype O127 : B8 and Group III: lung sepsis was induced as in group II then divided randomly into 3 subgroups. Subgroup IIIa: animals were injected with gentamicin, Subgroup IIIb: animals were injected with gentamicin and given virgin olive oil and Subgroup IIIc: animals were given virgin olive oil only. During the experiment the body weight and hemodynamic parameters were monitored. At the end of the experiment the lungs were excised out and processed. Histological and immunohistochemical studies of lung sepsis showed an alteration in the lung architecture in the form of overexpansion of alveoli alternating with collapse of others. Pneumocytes II showed destruction of lamellar bodies and were predominant replacing pneumocytes type I in the alveolar lining with increase in HSP70 expression, significant decrease in body weight and blood pressure with tachycardia. Gentamicin- treated group revealed minimal improvement in lung tissue. While concomitant administration of virgin olive oil along with gentamicin showed a noticeable improvement in lung architecture and increase in HSP70 expression with significant improvement of body weight and blood pressure. However animals given virgin olive oil only revealed the most favorable results with remarkable improvement of lung architecture. In conclusion, based on the previous findings, gentamicin and olive oil prevents the deleterious effects of lung sepsis. Moreover, virgin olive oil solely has succeeded to improve the septic effects on lung by enhancing anti-oxidant defense system and suppression of oxidative stress.

Abstract: Nicotine has been reported to cause deleterious changes on gastric mucosa such as gastritis, gastric ulcer and even has been well documented to be closely related to the development of gastric cancer. This study was carried out to evaluate the possible gastroprotective effect of curcumin along with its effect on cyclooxygenases against cytotoxicity of nicotine in gastric mucosa. Forty five adult male albino rats were randomly divided into three groups of fifteen animals in each group; group I (Control), group II: each rat was given oral nicotine (50 μg/ml) once daily, group III: each rat was given oral curcumin (200mg/kg) body weight once daily concomitant with nicotine with similar dose as group II. All animals were treated for 21 days and were sacrificed at the end. The stomach was processed for histological and immunohistochemical studies. Nicotine administration induced erosion and disruption of fundic gastric mucosa with exfoliated remnant of gastric glands associated with dilated, congested blood vessels and apical new vascularization. Marked decrease in PAS positive mucus with highly significant decrease in COX-1 expression and a highly significant increase in COX-2 expression were observed. Concomitant use of curcumin with nicotine showed considerable degree of preservation of gastric mucosa and PAS positive mucus. Anon significant decrease in COX-1 expression as well as a significant increase in COX-2 expression were observed. In conclusion, curcumin showed a protective role against the harmful effects of nicotine on the gastric mucosa.

Abstract: Adult male rats were exposed to heterogeneous chemical mixture (HCM) of Phthalic acid di butyl ester, 1, 2 –Dichlorobenzene, Cadmium chloride and Chromium trioxide, through oral gavage, at a dose level equal to 1/100 and 1/1000 of LD50 value of each chemical compound for 60 days followed by withdrawal of exposure until 120 day of experiment. Histological alterations, serum parameters of liver function and oxidative stress parameters in liver assessed the status of structure and function of liver following exposure. The increased serum liver marker enzyme activities and decreased endogenous antioxidant levels suggested that HCM exposure below individual chemical’s NOAEL doses significantly hamper the normal function of liver. This is well correlated with increased CHO, LDL and VLDL level because these appear harmless until they are in blood vessel walls and oxidised by free radicals. Thus, HCM exposure has a definite effect on liver structure and function. However, the low dose HCM induced changes are reversible and effectively reversed by withdrawal of treatment for comparatively longer duration of time.

Abstract: Thirty postpartum anestrus jersey crossbred cows were selected and divided into 3 groups with equal number of animals. The group 1 animals were administered with an intravaginal progesterone device (CIDR) on day 0 and 2 ml of Prostaglandin F2α on 7th day i.e., on day of CIDR removal whereas group 2 cows were treated with ovsynch protocol (GnRH - PGF2α- GnRH) on day 0, 7 and 9 respectively. The group 3 cows were supplemented with mineral mixture 100 gm daily for 15 days and treated as control. The animals were inseminated by frozen semen at a fixed time, 48 h after PGF2α injection in group 1 and 24 h after second GnRH injection in group 2. However, the group 3 animals were served by frozen semen at observed estrus. The study was conducted with an objective to determine the serum mineral concentration (serum calcium, serum phosphorus and their ratio) and cholesterol level. The serum cholesterol was estimated by CHOD/PAP method whereas the serum phosphorus concentration was estimated by molybdate U.V method and serum calcium concentration was done by OCPC method by using Coral kit. The absorbance of standard and test sample was measured against the blank by semi auto analyser at wavelength of 505nm, 340 nm and 570nm. There was no significant difference for serum calcium, phosphorus, cholesterol in postpartum anestrus cows irrespective of treatment protocols and days of sampling.

Abstract: The present experiment was undertaken to study the effect of summer and winter season on the hormone and enzymatic profile of cross-bred (HF X J) cattle in Assam. The different hormones such as Cortisol, T3 and T4 are estimated by RIA technique and the different enzyme activities such as SOD (Superoxide Dismutase), GSH-Px (Glutathione Peroxidase) and CAT (Catalase) are analysed by different standard methods while LDH (Lactate Dehydrogenase) activity was estimated by using commercially available kit. It has been observed that all the stress related hormones and the erythrocytic enzyme activities were increased in summer compared to winter season and the difference was highly significant (P<0.01). The increase in hormone concentration and enzyme activity might be attributed to the thermal stress in the summer.

Abstract: Purpose of the study was to evaluate the prognostic value of Ki 67 proliferation antigen in spontaneous canine cutaneous and subcutaneous tumours by immunohistochemistry. Formalin fixed, paraffin embedded histological sections were immunostained with monoclonal anti-human Ki 67 antibody (GM001). To determine Ki 67 index, approximately 1000 neoplastic cells were counted in 10 representative fields and number of positive cells per 1000 cells was expressed as percentage. Malignant tumours (64) had a mean Ki 67 index of 24.65 ± 1.69 while benign tumours had an index of 11.38 ± 2.61. Statistically significant difference (P < 0.05) was observed between malignant and benign types. The mean Ki 67 expression among the 12 dogs with malignant tumours that died was significantly (P < 0.05) higher (37.37 ± 4.32 per cent) compared to alive group. In 16 dogs with recurrence also the Ki 67 index was significantly (P < 0.05) higher (29.06 ± 2.74 per cent) as compared to alive group. The results of the current study indicated that poor prognosis was associated with higher Ki 67 index and the survival analysis, using Ki 67 index median cut off value indicated the prognostic importance of Ki 67 index in malignant cutaneous and subcutaneous tumours of dogs.

Abstract: Rice (Oryza sativa L.) is one of the most important food crops of Southeast Asia, which feeds half of the world population. Anther culture is an efficient and convenient technique for rapid production of doubled haploids which are useful in crop breeding programs. The combination of different growth regulators facilitates callus induction on N6 medium and regeneration on MS medium. Highest callus induction frequency was recorded in growth regulator concentrations of 2, 4-D 2.0 mg/l+ Kinetin 1.0 mg/l (34.54%) followed by in growth regulator concentrations 2, 4-D 1.0 mg/l + NAA 2.0 mg/l + Kinetin 0.5 mg/l (33.38%). Highest regeneration frequency was recorded in growth regulator concentrations of Kinetin 0.5 mg/l + BAP 2.0 mg/l + NAA 1.0 mg/l (69.44%) followed by in growth regulator concentrations of Kinetin 2.0 mg/l + BAP 1.0 mg/l + NAA 1.0 mg/l (40.00%). This is clearly indicated that type of growth regulator along with its concentration plays important role in callus induction and regeneration in japonica rice varieties.

Abstract: Bisphenol A (BPA) is an endocrine-disrupting molecule and can bind to α and β estrogen receptors and exerts its harmful effects. It is widely used in epoxy resins and polycarbonate plastics. Exposure to BPA can be associated with many health problems as abnormalities of reproductive system, cardiovascular disease, metabolic disorders, cancer and neurobehavioral disorders. Thymoquinone (TQ) have antioxidant, anticonvulsant, antitumor and anti-inflammatory effects, and may protect organs from oxidative damage by free radical generating agent. The objective of this study is to evaluate the protective effect of thymoquinone against BPA induced germ cell toxicity of adult male albino rats testis. In this study, forty adult male rats were used. They were divided into four groups (10 rats for each): group I (control group), group II (thymoquinone treated group), group III (bisphenol A treated group), group IV (bisphenol A and thymoquinone treated group). Testicular tissue were used for histological and immunohistochemical studies. Blood plasma was used for hormonal analysis. Administration of BPA significantly reduced seminiferous tubules diameter and epithelial height with impaired spermatogenesis, decreased plasma testosterone, FSH and LH levels. BPA caused decreased androgen receptors. Administration of thymoquinone with bisphenol A led to amelioration of these toxic effects. Thus exposure to BPA induces toxic effects on the testis with an imbalance in the hormonal levels, while thymoquinone could ameliorate these toxic effects.

Abstract: Paratuberculosis (Johne’s disease) is one of the major economically important disease of small ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP) – a slow growing acid fast bacterium. It causes granulomatous enterocolitis, lymphadenitis and lymphangitis in domestic and wild ruminants. The present study was conducted to record pathomorphological changes in naturally occurring ovine paratuberculosis in an organised sheep farm. The study included 36 paratuberculosis suspected morbid cases in an organised Bannur sheep farm in Mandya district, Karnataka, India. Clinical findings such as intermittent diarrhoea, jowl oedema, cachexia, anaemia, paleness of mucous membrane were recorded in paratuberculosis suspected cases. Out of 36 paratuberculosis suspected morbid cases, 12 showed gross lesions such as muscular atrophy, thickening and corrugation of intestines especially at ileocaecal junction, cording of mesenteric lymphatics with enlarged and oedematous lymph nodes. Gelatinous fat atrophy was very conspicuous in omental, mesenteric, pericardial and perirenal fat. Microscopically lesions were classified on the basis of their location in relation to intestinal lymphoid tissue, intensity, inflammatory cell types and numbers of mycobacteria. In four sheep, paucibacillary type of lesions were observed which were characterized by small granulomas in villi, lamina propria and lymphoid follicles. The granulomas contained few macrophages with clear and large nuclei and abundant cytoplasm with heavy infiltration of lymphocytes. Eight cases revealed mulitbacillary type of lesions with large granulomas characterized by extensive infiltration of macrophages and epitheloid cells along with acid fast organisms with few lymphocytes infiltration. In conclusion, ovine paratuberculosis was diagnosed based on classical gross and histopathological lesions were confirmed positive by IS900 specific PCR in an organised semi intensive sheep farm in Karnataka in Bannur sheep breed.
