Abstract: Gentamycin, a frequently used aminoglycoside antibiotics, has a nephrotoxic effect to human beings and animals. The purpose of this research was to find out the microscopic changes of wistar rat kidneys after gentamycin induction. This was an experimental study, using five adult wistar rats, divided into three groups. Group I was the control group; group II consisted of two rats, injected with gentamycin 0,3 ml/day (dose of 60 mg/kg body weight/day) intraperitoneally for seven days; and group III consisted of two rats, injected with gentamycin 0,3 ml/day intraperitoneally for 10 days. Group I and II were terminated at day-8, and group III at day-11. Their kidneys were processed for microscopic slides, stained with hematoxylin eosin and Periodic Acid Schiff. In microscopic evaluation, group II and III showed oedema, necrosis, apoptosis, and basal membrane destruction of tubular epithelial cells. Group III also showed fat vacuoles in these epithelial cells (macrovesicular fatty changes). Conclusion: wistar rats injected with gentamycin 60 mg/kg body weight/day for 7 and 10 days showed oedema, necrosis, apoptosis, and basal membrane destruction of tubular epithelial cells; and macrovesicular fatty changes after 10 days of gentamycin.Key words: gentamycin, necrosis tubular epithelial cells, fatty changesAbstrak: Gentamisin termasuk antibiotik golongan aminoglikosida berspektrum luas yang bersifat nefrotoksik terhadap manusia dan hewan.

Objectives: To evaluate the anti-oxidative role of Resveratrol in Cisplatin-induced testicular toxicity in Albino Wistar rats. Study Design: Quasi-experimental study. Settings: Department of Physiology and Postgraduate Laboratory of ISRA University Hyderabad. Period: Six months from March to September 2019. Material & Methods: Twenty-four male albino Wistar rats were distributed equally into; Group-I (Control), Group-II (Cisplatin), Group-III (Cisplatin + Resveratrol). Difference in mean pre and post-experimental body weight was observed while analysis of oxidative markers, semen parameters, and histomorphology was carried out in all three groups. SPSS ver. 22 was used to analyze the data. Results: The mean body weight decreased from 241.7±8.5 gm to 196.50±9.34 gm and from 237±7.4 gm to 210.0 ± 6.50gm in groups II and III respectively. Statistically significant reduction in semen parameters (sperm count, motility and viability) was observed in Group-II compared with Group-C (p<0.05). Oxidative markers were also significantly depleted in Group-II in comparison to Group-C (p<0.05). Histologically, testicular structure was found to be intact in Group-I. Marked changes were observed in testicular histology of Group-II while Group-III displayed less testicular damage. Irregular, regressive and atrophic seminiferous tubules were seen in Group-II. Most seminiferous tubules having normal morphology were observed in Group-III while the number of atrophic and degenerative seminiferous tubules also decreased significantly. Conclusion: Resveratrol therapy is a potent protective regime showing promising results in cisplatin-induced testicular toxicity and oxidative stress.

Abstract Objectives Exposure to light-at-night (LAN) has been reported to impair blood glucose regulation. The liver modulates blood glucose through mechanisms influenced by several factors that include peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1α) and glucose-6-phosphatase (G6Pase). This study investigated the effect of intermittent exposure to green and white LAN on some hepatic glucose regulatory factors in male Wistar rats. Methods Animals were divided into three equal groups. Group I (control) was exposed to normal housing conditions. Groups II and III were each daily exposed to either green or white LAN for 2 h (7–9 pm) for 14 days. Body weight and blood glucose was monitored on days 0, 7, and 14. Thereafter, retro-orbital sinus blood was obtained after light thiopental anaesthesia and serum insulin was determined. Liver samples were also obtained and evaluated for glycogen, PGC-1α, and G6Pase activity. Insulin resistance was estimated using the HOMA-IR equation. Results Body weight and blood glucose on days 7 and 14 increased in groups II and III compared to control. Hepatic PGC-1α and G6Pase increased in group II (2.33 ± 0.31; 2.07 ± 0.22) and III (2.31 ± 0.20; 0.98 ± 0.23) compared to control (1.73 ± 0.21; 0.47 ± 0.11). Hepatic glycogen was 71.8 and 82.4% reduced in groups II and III compared to control. Insulin in group II increased (63.6%) whiles group III values reduced (27.3%) compared to control. Insulin resistance increased in group II (0.29 ± 0.09) compared to control (0.12 ± 0.03) and group III (0.11 ± 0.03), respectively. Conclusions Exposure to 2 h green and white LAN in the early dark phase increases hepatic glycogenolysis and gluconeogenetic activities resulting in increased blood glucose. In male Wistar rats, exposure to green but not white LAN may predispose to insulin resistance.

The Difference

The monthly wool growth of three groups of rams was studied at Beltsville, Maryland. Group I received natural daylight (at 38° 53' N.) and was shorn monthly. Group II had a 7:17 hours of daylight to hours of darkness rhythm and was shorn every 6 months, once in winter and once in summer. Group III received natural daylight and was likewise shorn every 6 months. The rams of all groups produced more wool in summer than in winter. This difference was significant (P<0.001). The mean body weight and food intake were both greater in the winter months, which indicated that the seasonal rhythm of wool growth was not a consequence of poorer feeding in winter. The rams which were shorn monthly (group I) grew considerably more wool than the other two groups, but the difference was not statistically significant. The short-day treatment of group II did not increase the annual wool production nor decrease the seasonal rhythm of wool growth. The balance of evidence from this and other experiments indicates that temperature rather than light controls the seasonal rhythm of wool growth.

Trapadil (Mochida Pharmaceuticals, Japan), an antiplatelet drug, suppresses the growth of several cell types and is thought to antagonize platelet-derived growth factor. The effects of trapidil on mesangial-cell proliferation in glomerulonephritis induced by anti-thymocyte serum in Wistar rats were investigated. Control rats were treated with phosphate-buffered saline (group I); group II rats were injected with a single dose of anti-thymocyte serum (8 ml/kg body weight), and group III rats were treated with both a single dose of anti-thymocyte serum (8 ml/kg body weight) and with trapidil (5 mg/kg body weight/day). Three rats in each group were killed on day 3, and the other three on day 10. Control rats showed no significant histological changes on day 3 or day 10. In group II, on day 3, there was a marked decrease in glomerular cell numbers, with mesangiolysis. Histologically severe mesangial-cell proliferation with expansion of mesangial areas was noted on day 10. None of the rats in group III showed mesangial alterations, histologically, indicating that mesangial-cell proliferation was suppressed by trapidil. This suppression may result from antagonism of the binding of platelet derived growth factor to the specific surface receptors in the mesangial cells. Trapidil may have clinical value in the treatment of mesangial-cell proliferative glomerular diseases.

Background: The non-availability of the sophisticated anaesthetic machine and the necessary equipment to administer inhalant anaesthetic in the field hospitals make their use practically unfeasible for the field veterinarians. Therefore, the present study was undertaken to evaluate the effect of propofol, ketamine and their combination ‘Ketofol’ as a TIVA on certain haematological, serum biochemical and hormonal profiles in atropine and xylazine premedicated dogs. Methods: The study was conducted in eighteen clinical cases of dogs of either sex. The animals were randomly divided into three groups with six animals in each group. All the three groups were premedicated with Atropine sulphate @ 0.04mg/kg body weight and xylazine HCl @ 0.5mg/kg body weight intramuscularly. In group-I, propofol @ 5mg/kg body weight, in group-II, ketamine @ 5mg/kg body weight and in group-III, ketofol @ 4mg/kg body weight was administered intravenously for induction after 15 minutes of pre-anesthetic administration. Surgical anaesthesia was maintained for 90 minutes in all three groups viz. group-I, group-II and group-III with propofol @ 2.5mg/kg. b.w., ketamine @ 2.5mg/kg b.wt. and ketofol @ 2mg/kg b.wt. respectively by intermittent bolus injection (IBI) technique. Haematological, serum biochemical and hormonal profile were evaluated before administration of the anaesthetic agent (0 minutes) then at 15, 30, 60 and 90 minutes during and after administration of anaesthetic agents. Result: The study revealed that Hb, PCV and TEC were significantly decreased in all the groups at 60 mints and 30 mints respectively. The biochemical evaluation revealed that blood glucose level was significantly increased in all the groups until the end of the experiment. BUN and creatinine value was a significant increase in group-I and group-II than group-III at different time intervals up to the end of the experiment. In all the groups’ alanine aminotransferase (ALT) values significantly increased up to 60th minutes during TIVA whereas AST value was significantly increased in group-II at 30th and 60th minute of the experiment in compare to group-I and group-III. A higher level of cortisol values was recorded in group-I animals for the entire period of observation. There were no changes observed in the case of T3. Transient variables of haemato-biochemical have been reported following propofol, ketamine and their combination (ketofol) as total intravenous anaesthesia (TIVA). Thus, it has been concluded that diligent monitorization and electrolyte support are essential during the period of anaesthesia.

Olanzapine is an antipsychotic drug effective in the treatment of stress-associated psychiatric illnesses, but its effect on the spleen remains unclear. Vitamin C is essential for the optimum function of the immune system. We aim to investigate the effect of Olanzapine on spleen structures and to assess the protective effect of vitamin C. Forty adult male albino rats were divided into four groups: group (I), a control; group (II), rats were given vitamin C at 40 mg/kg body weight; group (III), rats were given Olanzapine at 2 mg/kg body weight; and group (IV), rats were given vitamin C and Olanzapine at the same dose of group (II) and group (III) for one month. The hematoxylin and eosin (H&E) of the olanzapine treated group showed focal areas of cellular depletion and a decrease in the size of the white pulp. The red pulp was expanded and showed marked congestion and dilatation of blood sinusoids. Cluster of differentiation 3 (CD3) was significantly reduced, however both tumor necrosis factor alpha (TNF-α), and vascular endothelial growth factor (VEGF) were significantly higher. The administration of vitamin C repaired structural and immunohistochemical changes via increased CD3 and decreased TNF-α and VEGF. Therefore, the oxidative and the inflammatory pathways may be the possible mechanisms underlying olanzapine immunotoxicity. Vitamin C exerted immune modulator and antioxidant effects against olanzapine.

The purpose of this study was to investigate the protective role of orally administered taurine against diabetic retinal changes via electroretinogram (ERG) and retinal histology on rabbits. Rabbits were randomly assigned into groups: Group I (vehicle administration only); Group II (diabetes: induced by 100 mg/kg alloxan injection); Group III (diabetes and fed with 200 mg/kg taurine); and Group IV (diabetes and fed with 400 mg/kg taurine). The body weight and blood glucose levels of the rabbits were monitored weekly. The ERG was measured on weeks 5 and 15. Retinal histology was analyzed in the end of the experiment. Results revealed that a taurine supplement significantly ameliorates the alloxan-induced hyperglycemia and protects the retina from electrophysiological changes. Group II showed a significant(P<0.05)change in the mean scotopic b-wave amplitude when compared to that of Group I, whereas the diabetic rabbits treated with taurine (Group III and IV) were analogous to Group I. Histologically, the amount of Bipolar and Müller cells showed no difference(P>0.05)between all groups and when compared with those of Group I. Our study provides solid evidences that taurine possesses an antidiabetic activity, reduced loss of body weight, and less electrophysiological changes of the diabetic retina.

Summary The effect of aqueous matured stem extract of Opuntia dillenii on selected biochemical parameters in Male Wistar rats was explored. Standard analytical methods were applied. Forty Wistar rats (80-100g) were used in the animal studies, separated into four groups. The control group was solely administered normal feed and saline, group I was administered 100mgkg−1 of the extract, group II received 300mgkg−1 of the extract and group III received 500 mg/kg−1 of the extract. A significant increase (p<0.05) in the activities of alanine aminotransferase (ALT) and alkaline phosphatase was observed in group II and III rats, as compared with the controls. A significant decrease in urea and creatinine concentrations was found only in group III rats against the controls. Also, a significant (p<0.05) decrease in triglyceride, total cholesterol, and low density lipoprotein (LDL)-cholesterol was seen in group II and group III rats when compared with the control. The hematological evaluation revealed a significant (p<0.05) decrease in red blood cell and hemoglobin levels in group III rats when compared with the control. The findings showed both beneficial and toxicological effects of the plant. Hence, for optimal therapeutic benefits, a further toxicological survey could still be carried out perhaps at higher doses.

Abstract: Liver is the largest organ in the abdominal cavity. As the center of metabolism in the body, liver is potentially damaged by exposure of toxic substances, inter alia carbon tetrachloride (CCl4). Metabolism of carbon tetrachloride (CCl4) produces CCl3 free radicals that can damage the liver. In Indonesia, there are a lot of natural ingredients that have antioxidant properties, such as tomato. Lycopene in tomatoes contains antioxidant compounds that can prevent damages due to free radical. This study aimed to obtain liver histopathological changes of wistar rats fed with tomato juice after being induced of carbon tetrachloride (CCl4). This was an experimental study, using 10 wistar rats which were divided into 4 groups. Group I was the negative control; group II was induced with CCl4 0,05 cc/day and was terminated on day 6; group III was induced with CCl4 0,05 cc/day and was given tomato juice 3 ml/day, and terminated on day 13; group IV was induced by CCl4 0,05 cc/day, given regular pellets, and terminated on day 13. The results showed that group II had histopathological changes of the liver indicating fatty liver, meanwhile group III showed regeneration of nearly all liver cells. Conclusion: Administration of tomato juice after the induction of 3 ml carbon tetrachloride (CCl4) for 7 day showed regeneration of almost all liver cells. Keywords: histopathological changes of the liver, carbon tetrachloride, tomato juice.   Abstrak: Hati merupakan organ terbesar dalam rongga abdomen, dan pusat metabolisme tubuh dengan fungsi yang sangat kompleks dan sangat berpotensi mengalami kerusakan akibat terpapar oleh bahan-bahan toksik, salah satunya yaitu karbon tertraklorida (CCL4).
