Fusarium Sp

Zearalenone (ZEA), a micotoxin produced by Fusarium sp. is regarded as a phytoestrogen. Although cytotoxic and genotoxic activity of ZEA was detected, the majority of its toxic influence is related to the ability of binding to estrogen receptors and disrupting the endocrine regulation of the reproductory functions in females. It was previously found that ZEA inhibits proliferation of cells in porcine ovaries, as detected with immunostaining for proliferating cells nuclear antigen (PCNA). The number of PCNA-positive cells was inversely proportional to the dose of ZEA. We decided to answer the question of whether ZEA induces apoptosis in porcine ovaries. Experimental gilts (before first estrus) were fed ZEA in a dosage of 20 (group II) or 40 (group III) µg/kg of body weight/day for 63 days. Control animals (group I) were fed a placebo. After that period animals were sacrificed, ovaries were extirpated, fixed in paraformaldehyde solution, cut into sections with a cryostat and studied for apoptosis with TUNEL kit, and for the presence of apoptosis-promoting protein Bax with immunohistochemistry. It was found that apoptosis was detected with TUNEL only in medium-sized antral ovarian follicles in animals of groups I and II. No apoptosis signal was found in the ovaries of animals in group III. No differences in the distribution and intensity of staining for Bax were found between animals of all investigated groups. The results indicate that ZEA do not induce apoptosis in porcine ovaries, and the inhibition of proliferation must be associated with other mechanisms.

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.

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.

BACKGROUND: Mastitis is an inflammation of the breast tissue, usually caused by bacteria. Mastitis stimulates pro-inflammatory cytokines. The cytokine interleukin-1β (IL-1β) is a crucial mediator of the inflammatory response. This cytokine has adverse effects of hosting immunity that mediates resistance to pathogens and also exacerbates damage during chronic disease and acute tissue injury. Scaevola taccada (Gaertn.) Roxb. has been used as an ethnomedicine for healing sores in several provinces in Indonesia. AIM: This study aimed to assess the profile of pro-inflammatory cytokine IL-1β through the treatment effect of leaf extracts of S. taccada (Gaertn.) Roxb. as adjuvant for healing mastitis. METHODS: This study was a true control group experiment using the pre-test-post-test control design aimed to measure the effect of hydroalcoholic compounds in leaf extracts of S. taccada on the systemic pro-inflammatory activity of interleukin-1β (IL-1β). The treated animals were 18 mice of Sprague Dawley strain induced by Staphylococcus aureus. These treated mice were divided into three groups in which each group consisted of six mice. The mice in the Group I (negative control) were given 1 ml aquabides/250 g body weight, those in the Group II (positive control) were delivered with 9.6 mg/ml amoxicillin/250 g body weight, and those in the Group III (experimental) were given 9.6 mg amoxicillin/250 g body weight + 400 mg/ml leaf extracts of S. taccada/g body weight for 5 days, respectively. Pathological examinations were carried out from the inflamed tissues to prove the healing process of the treated mice. IL-1Β levels were determined using the enzyme-linked immunosorbent assay method. Data were analyzed using ANOVA and post hoc tests. RESULTS: There were statistically significant differences of IL-1β levels after the administration of leaf extracts of S. taccada among all the treated mice groups at p < 0.05. The Group III had the lowest IL-1β level with the mean value ± 1.45 pg/ml compared to the IL-1β level in the Group II (positive control) with the mean value ± 3.82 pg/ml and the IL-1β level in the Group I (negative control) with the with mean value ± 5.22 pg/ml. The pathological analysis of breast tissues of the treated mice proved that leaf extracts of S. taccada (Gaertn Roxb.) could reduce damaged tissues, cellular infiltration, and subcutaneous edema induced by this pathogenic microorganism. CONCLUSION: Leaf extracts of S. taccada had a significant function as adjuvant for healing mastitis by reducing pro-inflammatory cytokine IL-1β.

The aim of the 21 day toxicity study was to evaluate the pathomorphological effect of flunixin meglumine in layer chicks. The chicks of Group I were kept as control while groups II, III and IV were fed with diet containing flunixin meglumine @ 10 ppm, 25 ppm and 50 ppm respectively for 21 days. Clinical signs viz. anorexia, dullness,lethargy, lameness and uneven growth were noticed in chicks of treatment groups III and IV only. Maximum mortality was observed in group IV (12%) followed by group III (4%). A dose dependant reduction in body weight was observed in all the treatment groups. The mean values of Kidney: Body weight ratio was significantly increased in group IV. The plasma uric acid, creatinine and BUN values were significantly increased in group III whereas increase in group IV was highly significant. Grossly, there was deposition of chalky white urates on serosal surface of kidney, heart and liver in chicks of group IV which died during experiment. Microscopically, lesions were characterized by varying degrees of congestion, haemorrhages, degeneration, necrosis and deposition of urate crystals in visceral organs of group III and group IV chicks. The intensity and distribution of pathological lesions were more severe in chicks of group IV, followed by chicks of group III. The overall lesions gave an impression that flunixin meglumine was nephrotoxic in nature.

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.

The objective of the study was to ascertain antioxidant, anti-inflammatory and cytokine gene regulation activity of Holarrhena antidysenterica (HA) in dinitrobenzene sulfonic acid (DNBS) induced inflammatory bowel disease (IBD) in rats. Sprague Dawley rats were divided into 6 groups, Group I (normal), Group II (50% ethanol intracolonically on 11th day), Group III (Model). Group IV to VI were given standard drug 5-amino salicylic acid (5-ASA) (100mg/kg) and hydromethanolic extract of Holarrhena antidysenterica (MEHA) 450 mg/kg and MEHA 600 mg/kg respectively for 18 days once p.o. Colitis was induced with DNBS (180mg/kg in 50% ethanol) intracolonically in animals of Group III-VI on 11th day. Body weight, food & water intake and stool consistency of each group was noted. On 18th day, blood was collected for cortisol estimation. Colon length and weight was measured. Cytokine gene expression studies of colon in group I, II, III, IV and VI was done using Real Time RT-PCR. Colon histopathology, Disease Activity Index (DAI) and Colon Mucosal Disease index (CMDI) parameters were studied. Nitric oxide (NO), malondialdehyde (MDA), myeloperoxidase (MPO) and superoxide dismutase (SOD) were estimated in colon homogenate. DNBS model control showed significant reduction in body weight, water and food intake, SOD, colon length and significant increase in stool consistency, colon weight, MDA, MPO, NO, CMDI, DAI, cortisol, IL-4, IL-6, IL-12 and IFN-gamma cytokines gene expression. Pretreatment with 5-ASA (100mg/kg) and MEHA (450 and 600 mg/kg) significantly reversed the above. MEHA reduced severity of IBD induced by DNBS through its anti-inflammatory, antioxidant and gene modulatory activity.

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.
