This works aims to study morphofunctional changes in the vessels of the oral mucosa during regeneration of a wound defect with and without a polymer membrane.An experiment was carried out on 35 white Wistar rats divided into three groups: control, experimental 1 and experimental 2. To form a wound defect, a flap of the oral mucosa was excised, which was covered by a polymeric piezoelectric membrane in the rats of group 2. Histological examination was carried out on the 3rd, 7th and 12th days: the control material was taken, histological preparations were made according to the standard method. In the lesion focus and surrounding tissues, specific areas and numerical densities of arterioles, venules and capillaries were determined; the pericapillary diffusion index, Kernogan index and arterio-venular ratio were calculated.On the 3rd day, all indicators in all experimental groups did not significantly differ from each other, but had significant differences from the control group. On the 7th day of the study, in the 1st group, the numerical density of open arterioles and venules corresponded to the control group. In group 2, the numerical density of capillaries and altered venules, as well as the index of pericapillary diffusion, significantly differed from the control. On the 12th day of the study, the numerical density of open venules reached control values in the uncoated group. In the 2nd group, all indicators corresponded to the control values.Protection of the wound defect from microbial contamination and re-traumatization, the presence of piezoelectric properties of the membrane under study contributed to a more effective restoration of vessels. This confirms the efficacy of the membrane under study when used as a wound covering.

The objective of this study was to evaluate the cellular proliferative potential of oral lichen planus (OLP) lesions from patients without hepatitis C virus (HCV) by means of AgNOR method, as well as the cellular proliferative potential of the normal oral mucosa from patients with HCV, treated or untreated by interferon and ribavirin. A cross-sectional study was developed to investigate four groups: 10 HCV+ patients without clinical signs of OLP who had never been treated for HCV infection - Group 1; 10 HCV+ patients that were under interferon and ribavirin treatment - Group 2; 15 patients with reticular OLP lesions histopathologically confirmed, without HCV - Group 3; and 15 blood donors without HCV infection and no clinical signs of OLP GROUP 4 Control Group. The cytological material of all groups was collected by the liquid-based cytology technique. Then, the sedimented material from each patient was filled with the Nucleolar Organizer Regions impregnation by silver method (AgNOR). The count of NORs was performed on 100 epithelial cell nuclei per patient using the Image Tool(tm) software. The Tukey HSD test was used to compare the median value of NORs among the groups and showed that the oral mucosa of HCV+ patients previously treated with anti-HCV drugs (GROUP 2), presented a higher average number of NORs in relation to others (p<0.05). The anti-HCV treatment may be related to increased cell proliferation of oral mucosa, indicating a possible relationship between OLP and HCV+ patients treated with interferon and ribavirin.

BACKGROUND: Immunological mechanisms of infertility are still poorly understood and controversial, both the cause and treatment. Inflammation, immunology, cell proliferation, cell differentiation, and cell survival are influenced by several proteins, including nuclear factor kappa-B (NFĸB), tumor necrosis factor-α (TNF-α), and interleukin-10 (IL-10). AIM: This study aimed to explore the potential of nano curcumin to prevent anti-sperm antibodies (ASA) formation due to the testes’ inflammatory process in Wistar rats. METHODS: This research is an experimental study with a pre-post-test approach with control group. The research subjects were rats (Rattus norvegicus) of the Wistar strain. The induced animals were grouped into three groups: Group 1 received nano curcumin 1 × 80 mg/kg BW orally, Group 2 received dexamethasone 1 × 0.3 mg/kg BW, and Group 3 received placebo aquadest 1 × 1 mL orally. TNF-α, NF-kB, and IL10 levels in serum were examined with enzyme-linked immunosorbent assay. RESULTS: The nano curcumin treatment showed the ability to reduce the pro-inflammatory cytokine protein TNF-α expression (47.3 ± 2.32) more optimally than dexamethasone treatment (54.4 ± 3.22). Nano curcumin has also shown the ability to reduce the pro-inflammatory cytokine transcription factor, NF-kB (32.5 ± 2.76) more optimally than treatment with dexamethasone (44.6 ± 2.43). CONCLUSION: Nano curcumin can prevent the formation of ASA in testicular trauma through inhibition of the inflammatory response.

Solanum gilo (eggplant) is an edible vegetable whose leaf is reported to possess numerous medicinal properties due to its rich constituents. Against this backdrop, there is possibility that its consumption may have effect on haematological indices. Therefore this research sought to assess the effect of Solanum gilo leaf diet on some haemotological indices of albino wistar rats. About twenty four (24) albino wistar rats weighing between 120-150mg were randomly assigned into four groups of six animals each. Each rat was allowed to drinking water ad labitum. Control group received normal rodent chow while group 2 was fed 5% Solanum gilo diet. Group 3 was fed 10% Solanum gilo diet and group 4 received 20% Solanum gilo diet. The different diets were prepared by mixing different proportions of ground S. gilo leaves with rodent chow. Automated blood cell analyzer (Model PCE 210, Japan) was used for analysis of haematological parameters. Preliminary study on its proximate composition, showed the appreciable presence of crude fat, protein, fibre and carbohydrate. Consumption of S. gilo caused significant improvement in some blood parameters; notably packed cell volume (PCV), white blood cell (WBC) and platelet counts. Hence, eggplant is a nutritious vegetable with healing, the therapeutic and immunity properties. If exploited in human diet has the potentials of improving quality of life.

The identification of a suitable prevention method which facilitates limiting the deleterious effects of acute kidney injuries is highly required. In order to identify a proper treatment for acute kidney injuries, a suitable experimental model that replicates the structural, metabolic and inflammatory lesions that occur in the natural acute injured kidney is highly necessary. Intense urinary NAG activity can be found in a variety of renal disease such as toxic nephropathies, ischemic renal injury following cardiac surgery or renal transplantation but also in glomerular disease especially in diabetic nephropathy. Rises in urinary NAG enzyme activity strongly suggests tubular cell damage and support NAG enzyme as a biomarker of renal tubular injury. The aim of this paper is to obtain a stable in vivo acute kidney injury experimental model, in Wistar, rats and to evaluate the urinary activity of N-acetyl-β-D-glucosaminidase (NAG) enzyme, blood levels of urea and creatinine and microstructural renal alterations induced by ischemia/reperfusion injury respectively gentamicin nephrotoxicity. For this purpose we have used a rat experimental model. Adult male Wistar rats weighing 250-300 g were randomly divided into 3 groups with 8 rats in each group. Group 1 served as a model for the renal ischemia/reperfusion injury experiment, group 2 served for toxic kidney injury experimental model and group 3 served as control group. All individuals in both groups 1 and 2 presented marked elevations in blood urea and creatinine at the moment of euthanasia (day 3 for group 1 and day 9 for group 2) compared to the control group where biochemical values remained within normal limits. Urine analysis of both group 1 and 2 showed marked urinary NAG index activity which suggests acute tubular injury, suggestion confirmed by histological evaluation of the renal parenchyma sampled from this subjects

Aloe vera has been the most useful medicinal herb in the world since ancient times due to its vast biological effects. The presence of high content of bioactive compounds make Aloe vera a promising complementary and alternative agent in disease prevention. The effectiveness of A. vera-based medicines against pesticide toxicity has never been evaluated. It was therefore envisaged to develop an A. vera-based strategy to protect the non-target animals from adverse effects of the pesticides. This article illustrates the ameliorating effect of aqueous extract (AE) of A. vera leaves against the cartap and malathion toxicity. To evaluate the protective impact of A. vera against cartap (Ctp), malathion (Mtn) and a mixture of both pesticides, the animals were divided in eight groups, each containing six rats: Group 1- C (control), Group 2- AE + C, Group 3- Ctp, Group 4- Mtn, Group 5- Ctp + Mtn, Group 6- AE + Ctp, Group 7- AE + Mtn, Group 8- AE + Ctp + Mtn. Wistar rats exposed to Ctp, Mtn and Ctp + Mtn, displayed significant change in body weight. It was observed that the WBC level increased significantly in Mtn and Ctp + Mtn challenged groups. The contents of TNF-α and IL-6 in serum increased expressively in the Ctp, Mtn and Ctp + Mtn challenged groups. Rats treated with Ctp, Mtn and Ctp + Mtn displayed significant alterations in the levels of antioxidative indices (MDA, GSH, GST, GPx, SOD and CAT). Significant alterations were recorded in the activities of AST, ALT, ACP and ALP in Ctp, Mtn and Ctp + Mtn challenged groups. The histopathological results of liver supported the biochemical data. The pre-treatment of rats with the aqueous extract of A. vera leaves significantly protected them from the toxicity of pesticides. These results suggested that A. vera extract may be used as a promising natural agent for the management of pesticide induced toxicity.

OBJECTIVE: Surgical scar tensile strength may be influenced by several factors such as drugs, hormones and diet. The purpose of the present study was to determine the influence of a shrimp-enriched diet on the tensile strength of rat scars. METHODS: Forty male Wistar rats were submitted to a 4 cm dorsal skin incision and the wounds were sutured with 5-0 nylon interrupted suture. The animals were divided into two groups: Group 1 (control) received a regular diet, and Group 2 (experimental) received a shrimp-enriched diet. The two diets contained the same amounts of proteins, lipids and carbohydrates. The rats in each group were divided into two subgroups according to the time of assessment of the scar tensile strength: subgroup A, studied on the 5th postoperative day, and subgroup B, studied on the 21st postoperative day. RESULTS: The tensile strength of the scar on the 5th postoperative day was lower in the animals that received the shrimp-enriched-diet (303.0, standard error of mean= 34.1) than in the control group (460.1, SEM = 56.7) (p<0.05). CONCLUSION: A shrimp diet reduces the tensile strength of the scar. The next step of this study will be to clarify the mechanism in which shrimp affects tensile strength.

AbstractParacetamol is extensively consumed as an analgesic and antipyretic drug, but at a high dose level, it leads to deleterious side effects, such as hepatic and nephrotoxicity. This research aimed to estimate the prophylactic efficacy of Chlorella vulgaris and/or thiamine against paracetamol (P) induced hepatorenal and cardiac toxicity. Forty-eight female Wistar rats were randomly divided into eight equal groups (n = 6 rats). Group 1, normal control group. Group 2, Paracetamol group. Groups 3, 4 and 5 were treated with Silymarin drug, Chlorella vulgaris alga, Chlorella vulgaris alga supplemented with thiamine, respectively daily for 7 successive days, then all were administered Paracetamol (2gm/kg. bwt.). While, Groups 6, 7 and 8 were treated by Silymarin, Chlorella vulgaris alga, Chlorella vulgaris supplemented with thiamine, respectively daily for 7 successive days without paracetamol administration. Our results clarified that Paracetamol toxicity caused significant adverse effects on hematological, serum biochemical parameters, and oxidant -antioxidant status as well as histopathological picture of heart, liver, and kidney. However, in the Paracetamol intoxicated groups pretreatment either with Chlorella vulgaris alone or plus thiamine successfully improved the undesirable deleterious effects of paracetamol, and restored almost all variables to near their control levels. This study has finished to that oxidative stress participates in the pathogenesis of paracetamol-induced toxicity in rats and using Chlorella vulgaris alga either alone or plus thiamine alongside their health benefits can protect against oxidative harmful effects induced by paracetamol through their free radical scavenging and powerful antioxidant effects, and they can be used as propylactic agents against paracetamol-induced toxicity.

Abstract: The coffee beans composed of the compound caffeine, palmitic acid, linoleic acid and acid stearic. The content of caffeine in coffee can improve spermatozoa motility that are not motile by inhibiting cyclic nucleotide phosphodiesterase and affects the intracellular levels of cyclic AMP. Spermatozoa quality can be affected by various factors such as stress. In nocturnal animals, dark periode becomes a signal to do activity by suprachiasmatic nucleus. The change in activity of the nocturnal animals from initial condition in the dark then exposed to light can leads to stress. This study was aimed to determine the effect of coffee on the spermatozoa quality of wistar rats which had been exposed to stress. This was an experimental analytical study with a post-test only control group design. The study was conducted for 50 days from September to November 2016. The sample consisted of 9 rats divided into three groups: a control group (P0) is given only exposure to stress in the form of light, the treatment group 1 (P1) is given exposure to stress in the light form and liquid coffee 1 ml / kg and the treatment group 2 (P2) is given exposure to stress in the light form and coffee extracts. The results showed that there were significant differences in the concentration and motility treatment group 1 (P1) to the control group (P0) which is p <0.05 and significant differences in sperm motility treatment group 2 (P2) to the control group (P0) which is p <0.05. Conclusion: Coffee administration could improve the quality of spermatozoa of wistar rats exposed to stress.Keywords: stress, coffee, quality of spermatozoa. Abstrak: Biji kopi tersusun dari senyawa kafein, asam palmatik, asam linoleat dan asam stearik.
