The aim was to study the protective effect of ethanolic extract of Achillea millefolium on acute vascular injuries induced by cisplatin in liver, heart and renal tissues 24 hour after administration and using histopathological surveys in wistar rats. 24 adult male wistar rats were randomly divided into four groups. Group I (control group) received physiological saline for 10 days. Animals of group II had single dose of injection of CP (cisplatin) (6 mg/kg, IP) on the ninth day. Group III received Achillea millefolium extract (250 mg/kg, gavage) for 10 consecutive days. Group IV had both Achillea millefolium extract (250 mg/kg, gavage) for 10 consecutive days and a single dose of injection of CP (6 mg/kg, IP) on the ninth day. Kidney, liver and heart organs were collected on 10th day from sacrificed rats and subjected to histopathological analysis. Then the possible histopathological vascular effects of cisplatin on liver, heart, kidney tissues and the protective effect of Achillea millefolium extract was analysed. Obtained data showed the vascular injuries in CP group as congestion of cardiac capillaries (p=0.00) and interstitial edema (p=0.03). In the kidney, shrinkage of glomeruli (p=0.04), widening of Bowman's space (p=0.04), dilatation of cortical capillaries (p=0.01) were significantly altered. The findings of liver organ were increased sinusoidal space (p=0.00) and infiltration of neutrophils in portal space (p=0.01). Pretreatment with ethanolic extract of Achillea millefolium could attenuate these vascular injuries. Briefly, 24 hour after single injection of cisplatin the inflammatory process was seen in vital organs and administration of Achillea millefolium could mitigate these side effects.

To evaluate the effects of Calcium carbide (CaC2) in biological system, an in vivo study was carried out on Long Evans rats. CaC2 was administered orally once daily for one month with specific concentrations. Group- I was considered as the control group (without CaC2), Group - II, III, IV and V were the sample groups treated with CaC2 having concentration of 1g/kg, 2g/kg, 5g/kg and 10g/kg body weight respectively. The experiment was conducted to detect any cellular and molecular level changes caused by CaC2. The histopathology and isozyme assay were performed to analyze the changes in the activities of the genes affected by the free radicals released from CaC2. The molecular analysis included different isozymes namely esterase and acid phosphatase. Polyacrylamide electrophoresis of whole cell extract of control subjects and CaC2 administered rats were performed; subsequently the gels were treated with the substrates for acid phosphatase and esterase respectively. No difference was observed in the whole cell extract band pattern between the control subject and the CaC2 administered rats, which grossly indicates that the CaC2 has no effect on the expression pattern of isozymes (acid phosphatase and esterase). Histopathological analysis of liver, heart, spleen, kidney and lungs were performed to observe any change due to the administration of CaC2. Remarkable changes were observed during the histopathological study of lungs and kidney only. The histopathological analysis of kidney showed the thickening of the lining of collecting tubules with changes in cell structure while lungs were found to be increased moderately in weight, with focal areas of consolidation that was found red-brown to red. Key words: Calcium carbide; Histopathological study; Isozymes Dhaka Univ. J. Pharm. Sci. 6(2): 93-98, 2007 (December)

In recent years more attention has been given to herbal drugs in the treatment and prevention of drug toxicity because of the harmful effects of chemical drugs. In this study, directed for this purpose, research was conducted on the protective effect of hydro-ethanolic extract of saffron petals (SPE) against acetaminophen (APAP) induced acute nephrotoxicity. Twenty-four male Wistar rats were distributed into four groups of six each. Group I, as a control group, received normal saline (0.09%) orally (PO). Group II, as an intoxicated group was treated with APAP, PO (600 mg/kg). In the groups III and IV, SPE in a dose of 10 and 20 mg/kg along with APAP (600 mg/kg) was administered, respectively. At the end of the trial (8th day), blood was taken from the heart of rats for assessment of biochemical parameters and the right kidney was placed in 10% buffered formalin for histopathological evaluations. In the APAP treatment group, higher serum creatinine and uric acid were observed. SPE in a dose of 20 mg/kg significantly reduced serum creatinine and uric acid. In pathologic evaluation, a dose of 20 mg/kg of SPE prevented the kidney injuries induced by APAP. Tissues changes were in accordance with biochemical findings. It is likely that the SPE contributed to the prevention of acute nephrotoxicity induced by APAP.

Abstract Background Hepatorenal injuries and dyslipidemia are common global health challenges but medicinal plant extracts may have potential to prevent them. Thus, this study evaluated the protective effect of aqueous extract of Lophira lanceolata leaf (LLE) against cisplatin-induced hepatorenal injuries and dyslipidemia in albino Wistar rats. Methods Thirty rats were randomly divided into 6 groups of 5 rats each. Group I rats received distilled water and served as control, group II rats were given 5 mg/kg cisplatin (CIS) intraperitoneally, groups III and IV rats were treated with 200 and 400 mg/kg LLE respectively for 26 days by oral gavages while groups V and VI rats were treated with 200 and 400 mg/kg LLE respectively, followed by CIS on the 21st day as in group II. About 24 h after treatment, blood was collected from the rats; then serum was separated and used for estimations of biochemical parameters. The kidney and liver of rats were removed, rinsed in normal saline, stored in 10% formalin and used for histological analyses. Results The biomarkers of hepatic (Aminotransferases, Alkaline phosphatase and Bilirubin) and renal (urea and creatinine) injuries, and dyslipidemia (Total cholesterol, triglycerides and LDL-cholesterol) significantly (p < 0.05) increased in the rats exclusively exposed to cisplatin when compared with normal control. However, treatment of cisplatin-exposed rats with 200 and 400 mg/kg LLE significantly (p < 0.05) reduced the levels of these biomarkers of hepatorenal injuries and dyslipidemia when compared with cisplatin control. Photomicrographs showed pathological signs in the liver and kidney of rats exclusively exposed to cisplatin, but there was moderate protection of these tissues in the rats treated with LLE and cisplatin. Conclusion The current findings have shown that Lophira lanceolata leaf extract may provide moderate protection against cisplatin-induced hepatorenal injuries and dyslipidemia in albino Wistar rats.

Introduction and Aim: Wound healing is an integrated process of cellular and biochemical events in restoring the structural functionality of the damaged tissue caused due to wounds. In the present study, the wound healing potential of an ayurvedic polyherbal formulation, Amrit oil is tested on an experimental model of the excisional wound in Wistar rats and evaluated for its potent activity in wound repair. Materials and Methods: Wistar rats were randomly arranged into 4 groups with 6 in each. Excision wound was created on the dorsal side of the rats. Group-I was kept as a negative control, Group-II as reference control, treated with Betadine, Group-III received a tropical application of Amrit oil once in a day and Group- IV were subjected to tropical application of amrit oil twice or Bis in a day. The wound healing was assessed by percentage wound contraction, a period of epithelisation, histopathological analysis and expression of MMP- 2, MMP-8, KGF and HSP-90. Results: The effect produced by the ayurvedic polyherbal formulation (Amrit oil), in terms of percentage wound contraction, a period of epithelisation, biochemical gene expression (MMP2, MMP8, HSP90 and KGF) and histopathological analysis were comparable to that of standard drug betadine. This study reveals the healing potential of Amrit oil as compared to the positive control, betadine possibly due to the presence of the phytochemicals in a synergistic manner. Conclusion: This study revealed a tremendous healing potential of Amrit oil as compared to the positive control, betadine in a holistic manner, confirming the rationality of the traditional knowledge.

The present investigation was carried out to evaluate the hepatoprotective effect of probiotic fermented milk (FM) containing Lactobacillus rhamnosus GG and Lactobacillus casei strain Shirota, alone as well as in combination with chlorophyllin (CHL) as an antioxidant agent in male Wistar rats administered aflatoxin-B1 (AFB1). AFB1 was injected intraperitoneally at the rate of 450 μg/kg body weight per animal twice a week for 6 weeks, maintaining an equal time interval between the two consecutive AFB1 administrations. A total of 125 male Wistar rats were randomly allocated to five groups, each group having twenty-five animals. Group I was offered FM containing L. rhamnosus GG and L. casei strain Shirota. Group II was administered AFB1 and served as the control group; group III was administered FM-AFB1, in which besides administering AFB1, FM was also offered. Group IV was offered CHL and AFB1, and group V was offered both FM and CHL along with AFB1. The rats were euthanised at the 15th and 25th week of the experiment and examined for the biochemical and hepatopathological profile. A significant reduction in thiobarbituric acid-reactive substances (TBARS) was observed in the FM–CHL–AFB1 group compared with the AFB1 control group. FM alone or in combination with CHL was found to show a significant (P < 0·05) hepatoprotective effect by lowering the levels of TBARS and by enhancing the activities of antioxidant enzymes such as glutathione peroxidase, superoxide dismutase, catalase and glutathione-S-transferase, indicating that probiotic FM alone or in combination with CHL possesses a potent protective effect against AFB1-induced hepatic damage.

Background: Propolis is a natural biocompatible material that has been widely studied in dentistry because of its inflammatory, anti-microbial and immunomodulatory properties. One of the active components is caffeic acid phenethyl ester (CAPE). CAPE is effective in stimulating collagen as well as inhibiting the inflammation and degeneration of dental pulp. Purpose: To investigate the post-administration of propolis extract as pulp capping material enhances odontoblast-like cell thickness and type 1 collagen expression in Wistar rats (Rattus Norvegicus) Methods: This research was a true experimental design with a posttest-only control group design. Sixty-three Wistar rats were randomly divided into three groups, with each group consisting of 21 rats: Group I: Positive control; no capping material was administered; Group II: CAPE was administered; Group III: 11% of the propolis extract was administered. All samples were filled with glass ionomer cement. Seven rats from each group were sacrificed after days 7, 14 and 28 of post-pulp capping administration, and their afflicted teeth were subsequently extracted for histologic analysis. Results: No significant difference was seen in odontoblast-like cell thickness after the application of CAPE and propolis on days 7 and 14 (p > 0.05). However, a significant difference was noticed on day 28 (p < 0.05), with the thickness of odontoblast-like cell in CAPE being thinner than that in propolis. A significant difference in the expression of type 1 collagen was observed on days 7, 14 and 28 after the application of the propolis extract compared with CAPE (p < 0.05). Conclusion: The post-administration of propolis extract as a pulp capping material could enhance odontoblast-like cell thickness and type 1 collagen expression in Wistar rats.

Abstract: Papaya leaves contain several antioxidants (flavonoid, tanin, and vitamin C) which have antiatherogenic effects that may inhibit the progression of an atherosclerotic lesion. One of the risk factors causing atherosclerosis is the consumption of food containing highly saturated fatty acids e.g. lard. Low density lipoproteins (LDL) accumulate within the intima and then are oxidized (LDL-ox). This LDL-ox is ingested by macrophages, resulting in foam-cell formation (early lesion of atherosclerosis). This study aimed to find out the histological features of the aorta of wistar rats having lard diets without the addition of the papaya leaf extract; having lard diets along with the papaya leaf extract; and having lard diets followed by papaya leaf extract. This was an experimental study on 16 wistar rats divided into 4 groups: group I without treatment (negative control group), group II lard diet for 14 days (positive control group), group III lard diet with papaya leaf extract for 14 days (treatment group I), and group IV lard diet for 14 days, and then followed by papaya leaf extract for 14 days (treatment group II). It was found that the aorta of group I showed adipose cells in the intima and media layers; group II and III showed foam cells in both layers; and group IV showed foam cells in fewer numbers than group II. Conclusion: The aorta histological features of wistar rats given lard diets for 14 days, with or without papaya leaf extract, showed foam cells in the intima and media layers. Papaya leaf extraxt added to lard diets had no effect on decreasing foam cells (no protective effect), meanwhile papaya leaf extract following lard diets showed a reduction of foam cells (therapeutic effect). Keywords: papaya leaf, lard dietary, foam cells, wistar rat.   Abstrak: Daun pepaya mengandung antioksidan (flavonoid, vitamin C) yang berefek anti-aterogenik, sehingga diharapkan dapat menghambat perkembangan lesi aterosklerosis. Salah satu faktor risiko penyebab aterosklerosis yaitu makanan yang berkandungan tinggi asam lemak jenuh, antara lain lemak babi. Konsumsi lemak jenuh berlebihan dapat mengganggu fungsi sel endotel, sehingga lipoprotein berdensitas rendah (LDL) dapat masuk dan menjadi LDL teroksidasi (LDL-oks). Makrofag menangkap LDL-oks dan menjadi sel busa (lesi dini aterosklerosis). Penelitian ini bertujuan untuk mengetahui gambaran histologik aorta tikus wistar dengan diet lemak babi tanpa pemberian ekstrak daun pepaya, diet lemak babi bersamaan pemberian ekstrak daun pepaya, dan setelah diet lemak babi dilanjutkan pemberian ekstrak daun pepaya. Penelitian ini bersifat eksperimental. Subyek penelitian terdiri dari 16 ekor tikus wistar yang dibagi menjadi empat kelompok: kelompok I tanpa perlakuan (kelompok kontrol negatif); kelompok II dengan diet lemak babi selama 14 hari (kelompok kontrol positif); kelompok III dengan diet lemak babi serta pemberian ekstrak daun pepaya selama 14 hari (kelompok perlakuan I); dan kelompok IV dengan diet lemak babi selama 14 hari, dilanjutkan pemberian ekstrak daun pepaya selama 14 hari (kelompok perlakuan II). Hasil penelitian memperlihatkan gambaran histologi aorta kelompok I tampak perlemakan; pada kelompok II terdapat sel-sel busa; pada kelompok III masih terdapat sel-sel busa; dan pada kelompok IV terdapat sel-sel busa, namun dalam jumlah yang lebih sedikit dibandingkan pada gambaran kelompok II. Simpulan: Tikus wistar dengan diet lemak babi selama 14 hari, baik dengan maupun tanpa ekstrak daun pepaya, memperlihatkan gambaran histologik adanya sel-sel busa pada tunika intima dan tunika media aorta. Pemberian ekstrak daun pepaya bersamaan dengan diet lemak babi tidak berefek menurunkan jumlah sel busa (tidak ada efek protektif) sedangkan pemberian ekstrak daun pepaya setelah diet lemak babi berefek mengurangi jumlah sel-sel busa yang terbentuk (efek terapi). Kata kunci: daun pepaya, diet lemak babi, sel-sel busa, tikus wistar.

Abstract Introduction: AAzathioprine and Methotrexate are both used in the treatment of cancer; and are classified as cytotoxic drugs with reported adverse effects such as oxidative damage to the DNA/RNA, the testes and sperm cells. This study, therefore, tested the hypothesis that AAzathioprine and Methotrexate administrations impair the morphology and functions of the testes in adult male wistar rats. Methods: AAzathioprine (50-150mg per day) and Methotrexate (2.5mg per week) are used in the treatment of cancer in adult Man. We tested the hypothesis that AAzathioprine and Methotrexate impair the morphology and functions of testes in rats. Forty adult male wistar rats (150-230g) were employed in the study: Control Group I received physiological saline while Experimental Groups II - V received oral administrations of 5mg/kg/bodyweight of AAzathioprine per day, 15mg/kg/bodyweight of AAzathioprine per day, 8mg/kg/bodyweight of Methotrexate per week and 20mg/kg/bodyweight of Methotrexate per week respectively for 35 days. Results: Histological examinations of the testes of rats of Groups II - V showed dose-dependent morphological anomalies such as fewer collagen ibers of connective tissues, disrupted seminiferous tubules and scanty spermatozoa when compared to rats of Group I. Statistical analyses showed dose-dependent elevated levels (P≤0.05) of superoxide dismutase and malondialdehyde in testes homogenates of rats of Groups II - V when compared to rats of Group I. This implied increased oxidative stress in rats of Groups II - V. Evaluations of Follicle Stimulating Hormone and Testosterone showed dose-dependent significantly elevated levels (P≤0.05) in rats of Groups II - V when compared to rats of Group I. Conclusions: Our findings are consistent with the stated hypothesis.
