Placental Extract

Oncotherapeutics like doxorubicin can affect male gonads; as a result, it leads to infertility. This work was conducted to demonstrate the toxic effects of doxorubicin on testes of male albino rats. Fifty male albino rats aged 5-7 weeks were used in this study. The animals were randomly separated into 5 sets (each set containing ten rats). Group I received saline (i.p.) for 4 weeks. Group II was given doxorubicin (DOX), 5 mg/kg BW (i.p.) once/week for 4 weeks. Groups III and IV were treated in the same way as the DOX group, left for one week without medication, and then injected with mesenchymal stromal cells (MSCs) or human placental extract (HPE) therapy in a single dose of 5 × 10 6 in 200 ml PRP/week or 40 μl placental extract for 4 weeks via the caudal vein. Group V rats were treated in the same way as the DOX group also, left for one week without medication, and then injected with MSC+HPE. A significant decrease in serum testosterone, FSH, and LH levels was observed in rats treated with DOX compared to the control group. A significant elevation was recorded in rats treated with DOX+MSC or DOX+HPE when compared with the DOX group only. Rats that were given MSC+HPE after DOX intoxication showed a significant increase in hormone levels when compared to rats treated with either MSC or HPE. Light and electron microscopic examinations revealed that DOX intoxication initiated degenerative and necrotic changes in seminiferous tubules associated with partial or complete cessation of spermatogenesis. These effects were reversed by the effect of MSC or HPE. Coadministration of MSC and HPE even showed further improvement. Finally, we can say that doxorubicin has a deleterious impact on rat testes; however, therapeutic effects can be induced through MSC and/or HPE administration.

<p class="abstract"><strong>Background:</strong> Diabetic nephropathy (DN) has become one of the most common causes of end stage renal disease (ESRD). Hyperglycemia induces oxidative stress in renal tubular epithelial cells that initiate tubulointerstitial fibrosis, which is a characteristic feature of diabetic nephropathy that becomes progressively complicated by renal failure. Aim: To assess the effect of spironolactone (SPL) on WT-1 protein expression and ultrastructural changes associated with the progression of experimental diabetic nephropathy (DN).</p><p class="abstract"><strong>Methods:</strong> Forty female albino rats were divided into five groups. Group I (control group), Group II (untreated diabetic rats), Group III (insulin-treated diabetic rats), Group IV (spironolactone-treated diabetic rats) and Group V (insulin and spironolactone-treated diabetic rats). At the 4<sup>th</sup> and 8<sup>th</sup> weeks, 4 rats from each group were sacrificed and renal tissue and blood samples were obtained. The rats were anaesthetized using ether inhalation. Each kidney was longitudinally divided and processed for immunohistochemical analysis with rabbit polyclonal anti-WT-1 Antibody and electron microscopic examination.</p><p class="abstract"><strong>Results:</strong> Treatment of STZ-induced diabetic rats with insulin and spironolactone (Group V) showed improvement in renal corpuscles as well as their capsular space, the basement membrane became normal with preserved minor and major processes and subpodocytic space, most of the proximal convoluted tubules retained their brush border, and their cells showed normal euchromatic nuclei and scattered mitochondria with apical microvilli, which is similar to the findings of the control group. Quantitative analyses showed significant increase in area of fibrosis and focal thickening of the glomerular basement membrane in non-SPL treated groups. There was a marked decrease in proteinuria compared to other treated groups. The results were better after 8 weeks compared to those after 4 weeks.</p><strong>Conclusions:</strong> The administration of SPL significantly prevented the extent of interstitial fibrosis in the diabetic kidney.

Pyrethroid cyhalothrin (PC) is an insecticide that is used worldwide for pest control in agriculture and household use. Samoa extract (SE) is a potent antioxidant protecting cells from oxidative stress. The present study investigates the protective and therapeutic effect of SE on PC-induced changes in sperm quality in male rats. Fifty adult male albino rats were divided into five groups: group I: served as control; group II: received PC i.p. only (6.2 mg/kg b.wt.); group III: received SE only (100 mg/kg b.wt., p.o.) for eight weeks; group IV: received SE as a protective agent daily for eight weeks, then followed by the administration of PC (i.p.) three times a week for two weeks; group V: exposed to PC (i.p.) three times a week for two weeks, then treated with the SE daily for 8 weeks. Results showed that PC caused markedly impaired sperm quality (a count, viability, motility, and abnormality). Compared to PC-treated animals, SE in the protective group markedly restored the alteration of sperm indices. However, SE in the curative group was found to be less effective in restoring PC-induced alterations. In conclusion, the data of this study revealed that the SE as a protective agent is more effective than as a therapeutic agent. Keywords: Samoa; Pyrethroid; Sperm quality; Rat

The present study aimed to investigate the ameliorative effects of fenugreek seeds and curcumin on hematotoxicity induced by nicotine in male albino rats. 30 male F-344/NHsd Fischer rats, weighing from 180 to 200g were used in the present study. The animals were divided into five groups (6 rats for each); Group I (control group), Group II (nicotine treated group), Group III (nicotine/fenugreek seeds co-administered), Group IV (nicotine/curcumin co-administered), and Group V (nicotine/curcumin& fenugreek seeds co-administered). At the end of the experimentation and 24 hours after the last dose, all animals were anaesthetized with ether and blood samples were collected by heart puncture. The samples were collected in clean dry tubes containing the anticoagulant substance EDTA and used for the hematological studies. The results showed that the animals treated with nicotine for 4 weeks showed a significant decrease in RBCs count, hemoglobin concentration, hematocrit value, MCH, MCHC, and platelets count, and increased MCV and WBCs count as compared to the control group. Co-administration of nicotine with fenugreek and/or curcumin caused improvement in all hematological parameters when compared with nicotine group. It can be concluded that nicotine had a strong effect on the hematological parameters. The ingestion of fenugreek and/or curcumin prevent the hematoxicity induced by nicotine. The current study suggests that fenugreek and curcumin may be useful in combating free radical-induced hematotoxicity induced by nicotine.

Cisplatin is the most effective chemotherapeutic drug used to treat the several types of tumors. Fraxinus xanthoxyloides is a plant with several pharmacological and biological activities. This research was aimed to find the curative potential of F. xanthoxyloides extract to counter the cisplatin-induced testicular damage in albino rats. Male albino rats were used for this trial. Rats were distributed into eight equal groups. Group I: control, Group II: vehicle control; Group III: cisplatin (10 mg/kg i.p.); Group IV: cisplatin (10 mg/kg) and silymarin (100 mg/kg); Group V: cisplatin (10 mg/kg) and F. xanthoxyloides (200 mg/kg); Group VI: cisplatin (10 mg/kg) and F. xanthoxyloides (400 mg/kg); Group VII: F. xanthoxyloides (200 mg/kg) and Group VIII: F. xanthoxyloides (400 mg/kg). Rats were slaughtered on 46th day of the experiment and testes and blood samples were collected. Hormonal analysis, antioxidant enzymes and histopathological changes were assessed. Cisplatin treatment induced significant (P<0.05) reduction in LH, FSH and testosterone concentrations. Activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and glutathione reductase (GSR) were significantly (P<0.05) reduced while significant (P<0.05) increase in the thiobarbituric acid reactive substances (TBARS) level was observed. Cisplatin significantly (P<0.05) decreased the seminiferous tubules diameter, tunica albuginea height, epithelial height, spermatogonia, primary and secondary spermatocytes and spermatids while significantly (P<0.05) increased the interstitial spaces and tubular luminal diameter. Whereas F. xanthoxyloides restored all these damages and abnormalities to their normal level. It is concluded that F. xanthoxyloides extract have capability to ameliorate the cisplatin-induced testicular toxicity in male albino rats

Simvastatin is a drug acting on 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase enzyme leading to decrease of lipid level in plasma. Simvastatin is associated with pleiotropic effects such as cardioprotective, hepatoprotective, and nephroprotective effect. This study aimed to observe effect of supplementation of trigona honey on parameters of liver function (SGPT and SGOT) and kidney function (urea) in albino rats (Rattus norvegicus) given 40 mg/kg simvastatin. Twenty-four male albino rats were divided into 6 groups (n=4). Each group was administered different treatments for 15 days orally. Group I was put as health control without any treatment, group II was given sodium carboxymethylcellulose (1% b/v) as negative control, group III was given simvastatin at the dose of 40 mg/kg, group IV was administered simvastatin (40 mg/kg) and trigona honey (6.5% v/v), while group V and VI were administered simvastatin (40 mg/kg) and ubiquinone (1.43 mg/kg); and simvastatin (40 mg/kg), trigona honey (6.5% v/v), and ubiquinone (1.43 mg/kg), respectively. Upon the treatments, level of SGOT, SGPT, and ureum was determined. The data were analyzed by using Analysis of Variance (ANOVA) and Least Significant Difference tests (p=0.05). According to the analysis, it was concluded that supplementation of trigona honey in rats administered simvastatin showed significantly lower level of all parameters than groups of simvastatin and controls.

Background: Diabetes is a chronic metabolic disorder that continues to present a major worldwide health problem, characterized by absolute or relative deficiencies in insulin secretion and/or insulin action associated with chronic hyperglycaemia and disturbances of carbohydrate, lipid, and protein metabolism. It is fast growing disease, gains the status of a potential epidemic in India with prevalence of more than 62 million diabetic individuals currently diagnosed with the diabetes.Methods: The study was conducted at Department of Pharmacology, Kurnool Medical College, Kurnool for a period of 1 year from January 2017 to December 2018. Animals used were albino rats, of Wistar strain, weighing between 150-200gm of either sex. The animals were divided into six groups as: control group (I); pathogenic control group (II) injected intravenously (i.v.) with single dose of STZ (60mg/kg); Morus alba stem bark extract (group-III; 200mg/kg), and group-IV (400mg/kg); group-V animals treated with glibenclamide (5mg/kg, p.o.) following STZ treatment; group-VI, animals treated with bark extract per se (400 mg/kg).Results: The results of this study showed a significant decrease blood glucose level, glycosylated heamoglobin level, and reduction in glutathione and insulin level after STZ administration. These parameters were significantly (p<0.05) reversed by extracts dose dependently.Conclusions: Thus, authors conclude that M. alba stem bark extracts produced significant antidiabetic and antioxidant effect which might be due to the presence of bioactive components such as phenolic and flavonoid content in the extract. The study warrants the need for further evaluated in certain other models of diabetes.

It is anticipated that Japanese quail /Coturnix coturnix japonica/ will provide animal proteins in long term space flights. Consequently this species of birds is of research interest of international space program INTERCOSMOS. In the year 1987 we reported on an experiment /2/ in which the effect of chronic acceleration of 2 G hypergravitation, the hypodynamy and the simultaneous effect of chronic acceleration and the location in the centre of the turntable of the centrifuge on the protein fractions in skeletal muscles was studied. The ultrastructure of the heart muscle was now in this experiments examined as well.Japanese quail cockerels, aged 48 days were exposed to 2 G hypergravitation /group IV/ in a 6,4 m diameter centrifuge, to hypodynamy /group III/ and their combination /group V/, respectively for 6 days / Fig.1/. The hypodynamy in group III was achieved by suspending the birds in jackets without contact the floor. The group II was located in the centre ofthe turntable of the centrifuge. The control group I. was kept under normal conditions. The quantitative ultrastructure of myocard was evaluated by the methods of Weibel/3/ - this enables to determine the number, relative size and volume of mitochondria volume of single mitochondria, defficiency of mitochondrial cristae and volume of myofibrils.

Abstract Background Repairing urinary bladder (UB) defect by enterocystoplasty remains the gold standard surgical bladder reconstruction procedure to increase the capacity and compliance of dysfunctional bladders. However, many complications were recorded. Aim of the work This work aimed to compare the consequences of reconstruction of urinary bladder defect using untreated small intestinal submucosal (SIS) matrix versus seeded and unseeded decellularized SIS matrix. Material and Methods Fifty female albino rats were used in this study. The animals were divided into three groups: Group I (Control) included ten adult rats from which ileal tissue was obtained. Group II included ten adult rats in which their UB defect was repaired by untreated cellular SIS. Group III included twenty adult rats that were subdivided into two subgroups, 10 rats each; Subgroup IIIA where rats had their UB defect repaired by acellular SIS and subgroup IIIb where rats had their UB defect repaired by acellular SIS seeded with adipose mesenchymal stem cells (AMSCs).Ten young rats were used for preparation of AMSCs. Morphometric and statistical analysis were also performed. Results In rats where UB defect was repaired by untreated cellular SIS, the graft area showed loss of epithelial polarity, presence of intraepithelial cysts and occasional extension of urothelium to the outer surface forming fistula. There were areas of metaplasia with the appearance PAS positive cells. In the lamina propria, there was areas of lymphocytic infiltration together with significant increase in the collagen fiber deposition (p &lt; 0.05). There was a significant decrease thickness of muscle layer as compared to control (p &lt; 0.05). In rats where UB defect was repaired by acellular SIS, urothelium in the graft area showed occasional squamous metaplasia and often the urothelium extended to the deeper layers forming Brunn's nest. There was minimal muscle regeneration in the graft area. However, in rats where UB defect was repaired by acellular SIS seeded with AMSCs, the urothelium in the graft area was nearly similar to control group with uniform urothelium thickness, minimal collagen fibers deposition and thick muscle layer that showed no significant difference from the control (p &gt; 0.05). Conclusion Acellular SIS seeded with AMSCs showed better results compared to non-seeded and cellular SIS in reconstructing urinary bladder defects.
