A pathological study of bracken fern ( Pteridium aquilinium ) toxicity was conducted in rats. Twenty albino rats were randomly divided in to 4 groups. The first three groups were received diet containing 10 %, 20 % and 30 % bracken fern powder respectively. The fourth group was served as control. The experimental rats were sacrificed after one month. Gross and histopathological examination reveal lesions in many organs . Gross lesions revealed congestion of all internal organs, while the histopathological lesions were characterized by spongiosis, perivascular cuffing and astrocytosis in the brain. Swollen hepatocytes accompanied by vacuolation and fatty degeneration in the liver. Suppurative pneumonia with infiltration of inflammatory cells in the lungs. In the intestine, the villi were fused with a proliferation of cryptal enterocytes. Interstitial nephritis associated by degenerative changes in the renal tubular epithelial cells. Acute cystitis with edematous lamina propria and neutrophilic infiltration were seen in the urinary bladder. These lesions were more sever in the group 3 incomparism with group 1 and 2 . No lesions were observed in the control group

Background: Aspirin is amongst the most widely used drugs and has many adverse effects on gastric mucosa. Anti-inflammatory properties of Acacia catechu have been established already. Objective was to evaluate the histopathological changes induced by aspirin in the stomach of albino rats and to assess the protective effect of different doses of Acacia catechu.Methods: Experimental study Postgraduate Medical Institute, Lahore for 21 days. Forty-eight adult albino rats, both males and female, were divided into four groups A, B, C and D randomly; each comprising of 12 rats. Group A was control, group B was given aspirin 100 mg/kg and group C and D were given aspirin 100 mg/kg along with Acacia catechu 250 mg/kg and 500 mg/kg respectively by oral route. The rats from individual group were sacrificed on 3rd day, 7th day and 14th day and stomachs were examined under light microscope to observe the inflammatory cells infiltration.Results: Gross and microscopic findings on days 3, 7 and 14 were similar. Control groups A1, A2 and A3 showed normal healthy gastric mucosa and the least number of inflammatory cells. In group B, aspirin produced ulcerations and linear breaks; with highest inflammatory infiltrates. On microscopic examination, numerous inflammatory cells were noted. Group C and D rats had minimum ulcer index and fewer inflammatory cells.Conclusions: Acacia catechu has protective role against gastric injury by inhibiting inflammation.

The present investigation was aimed to determine the effect of sub-chronic exposure to Solignum<sup>®</sup>, a permethrin-containing wood preservative on biochemical and histological changes in liver and kidneys of male Wistar albino rats. Thirty-two male rats were randomly divided into four groups: control and three treatment concentrations containing 8 rats each. The treatment groups were exposed to Solignum<sup>®</sup> at dose rates of 100, 200 and 400 mg/kg body weight (BW) respectively per day orally for four weeks. Data obtained from the study showed a progressive increase in the body weight of rats in control whereas, rats treated with different concentrations (100, 200 and 400 mg/kg BW) of Solignum<sup>®</sup> decreased significantly (≤0.05) especially at the end of the second and fourth week when compared with control. On the other hand, there was a significant decrease in the relative liver weights of rats treated with 100 and 200 mg/kg BW Solignum<sup>®</sup> while rats treated with 400 mg/kg BW showed a significant increase when compared with control. The relative weight of kidneys in experimental groups increased significantly when compared with control. Biochemical analysis results illustrated that there was a significant increase in marker enzymes namely alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase activity at the end of the fourth week. Similarly, total bilirubin, serum urea, creatinine and electrolytes (Na<sup>+</sup>, K<sup>+</sup> and Cl<sup>-</sup>) levels increased in a dose dependent manner in treated rats when compared with untreated control group. Serum total protein decreased significantly in experimental rats when compared with control. However, cholesterol and triglycerides showed no significant difference when compared with control. Histopathological examination of hepatocytes in treated rats was characterized by mild periportal inflammatory cells and cytoplasmic degeneration. Furthermore, histopathological examination of rat kidneys revealed inflammatory cells, congested vessel and interstitial hemorrhage in rats treated with Solignum<sup>®</sup>. Therefore, this present study is aimed to evaluate the hepatotoxic and nephrotoxic potentials associated with sub-chronic exposure to the commercial pesticide Solignum<sup>®</sup>.

Background and Aims. Sepsis can evoke disseminated intravascular coagulation, resulting in multiple organ failure and death. Heme oxygenase-1 (HO-1) and hemopexin (HPx) can mediate cytoprotective mechanisms against these deleterious effects. This study aims to determine a role for HO-1 and HPx in coagulopathy induced by septic inflammation and define whether they can enhance the production of anti-inflammatory cytokine IL-10. Materials and Methods. 48 healthy male albino rats were divided equally into 4 groups: control group: animals subjected to laparotomy and bowel manipulation; CLP group: severe sepsis induced by cecal ligation puncture (CLP); CLP + hemin group: animals received single intraperitoneal injection of hemin (50 µmol/kg) 12 h before sepsis induction; CLP + HPx group: animals received single HPx dose (150 µg/rat, i.v.) 30 min before sepsis induction. Survival rates were calculated. Prothrombin time (PT), activated partial thromboplastin time (APTT), and activated protein C (APC), liver HO-1, serum, and liver IL-10 levels were measured, 48 hrs after sepsis induction. Liver and lung were excised for histopathological examination. Results. Hemin and HPx administration upregulated liver HO-1 and IL-10. They prolonged PT, PTT and increased APC. They reduced the inflammatory infiltrate and thrombosis in liver and lung parenchyma. However, hemin was superior in controlling coagulopathy and HO-1 production, while HPx was more potent stimulant of IL-10 expression. Conclusions. Hemin and HPx have a potential beneficial effect in severe sepsis regarding coagulopathy and inflammation.

BACKGROUND: Sofosbuvir (SOF) was published in 2013 as a part of first-line treatments for hepatitis C virus (HCV); it has activity against all genotypes with extrahepatic adverse effects have recently arisen. AIM: Investigating sofosbuvir-induced alterations in the rat submandibular salivary gland (SMSG). METHODS: A group of 80 adult albino rats weighing about ± 150 gm were used in the experiment. The rats were divided into 3 groups: Group I (control group) received distilled water, Group II (experimental group) divided into 2 subgroups and received SOF 40 mg/kg/day dissolved in distilled water for 1 and 3 months and Group III (recovery group) allowed for 1 month of recovery after SOF withdrawal. All animals were sacrificed; the SMSG was dissected, and specimens were examined histologically and ultra-structurally. RESULTS: Compared to Group I, Group II subgroup (1) showed acinar and ductal vacuolisation, discontinuity of the epithelial lining associated with retained secretion and congested blood vessels. These changes were found to be exaggerated in the subgroup (2) accompanied by acinar and ductal shrinkage, interstitial oedema, haemorrhage, chronic inflammatory cells infiltration and loss of gland compactness. Amelioration of the histological changes was detected in Group III after SOF withdrawal. The ultrastructural examination confirmed the histological results. CONCLUSION: SOF had induced apparent alterations in the structure and ultrastructure of SMSG. The SOF-induced alterations were time-dependent, attributed mainly to mitochondrial toxicity and partially ameliorated by its withdrawal.

Combretum collinum root extract has been recognized long ago as traditional medicinal plant in curing several diseases among the indigenous people of Alela-land (Zuru), Kebbi State, Nigeria. This research work was carried out to evaluate the toxicological effects of Combretum collinum methanol root extract (CCME) in albino rats. Acute toxicity was performed by a fixed single oral administration at a dose of 10, 100, 1000 mg/Kg and 1600, 2900, 5000 mg/Kg. Subchronic toxicity studies of CCME was conducted at doses of 32, 63, 126 and 253 mg/Kg for 28 days. The result showed that acute administration of CCME resulted at mortality and general behavioral changes at 1000 to 5000 mg/Kg. Therefore, the estimated lethal dose (LD50) of CCME was 316.23 mg/Kg. Subchronic oral administration of CCME revealed a significant (P<0.01) decrease in body weight in rats receiving 63 to 253 mg/Kg throughout the study period compared with the control group. The results also showed a significant (P<0.01) increase in serum ALT, AST, creatinine, potassium and bicarbonate in rats administered with 126 and 253 mg/Kg of the extract. Haematological analysis of the same extract revealed a significant (P<0.01) increase in WBC, HCT, MCV, MCH, MCHC, PLT, LYM and NEUT in rats receiving 126 and 253 mg/Kg only. Histopathological examination of liver revealed severe periportal inflammation, hypertrophy, areas of hydropic changes, cancerous tumor, areas of infiltration and necrosis of the hepatic cells while the kidney showed a mild mesengial hyperplasia, compressed blood vessels, glomerular degeneration, tubular degeneration and tubular widened lumen in rats treated with 63 to 253 mg/Kg. Therefore, caution should be applied as C. collinum root extract has a low mean lethal dose and would be toxic at higher concentrations.

Background: The present study was designed to evaluate the relative ameliorating efficacy of lycopene against the deleterious effects of boldenone, an androgenic steroid, on the rat testis and kidney.  Materials and Methods: 40 male albino rats were divided into four groups; control group received intramuscular (i.m) injection of olive oil once a week; lycopene (Lc) group received lycopene (10 mg/kg b.w p.o daily); boldenone (Bol) group received (5 mg/kg b.w i.m once a week); Bol + Lc group received boldenone (5 mg/kg b.w i.m once a week) and lycopene (10 mg/kg b.w p.o daily) all for four weeks. Results: intramuscular injection of boldenone significantly induced lipid peroxidation and DNA fragmentation as well as inhibited total antioxidant capacity (TAC) and catalase (CAT) activity in testis and kidney tissue. Additionally, up-regulation of Bax and down-regulation of Bcl-2 gene expression after Bol injection along with marked increase in serum inflammatory cytokines and decrease in serum testosterone. These alterations were confirmed by the histopathological examination of testis and kidney. On the other hand, lycopene oral administration attenuated the testicular and renal injuries induced by boldenone injection. Conclusion: administration of antioxidants as lycopene effectively ameliorated the adverse effects of boldenone on testis and kidney tissues. Key words: Boldenone undecylenate, lycopene, DNA fragmentation, interleukin-1β, tumor necrosis factor-α, apoptosis.

BACKGROUND There is no in vivo evidence for the effectiveness of adjuvant intrastromal and combination of intrastromal and intracameral voriconazole (VCZ) for treating Aspergillus fumigatus keratitis. This study aimed to compare the efficacy of both agents against it.  METHODS A randomized, masked, controlled experimental study was conducted on 11 albino New Zealand white rabbits in which moderate fungal keratitis was induced by inoculating spores of A. fumigatus to the cornea. The rabbits were allocated into 3 groups: 50 μg/0.1 ml intrastromal VCZ injection, 50 μg/0.1 ml intrastromal VCZ and intracameral VCZ injections, and topical VCZ (control). The treatment was given 5 days after inoculation. Epithelial defect, infiltrate size, corneal ulcer depth, and hypopyon were evaluated clinically. Histopathological and mycological examinations were also done 14 days after treatment.  RESULTS All rabbits in the adjuvant treatment groups demonstrated a tendency of a better clinical response with decreasing size of epithelial defect (p = 0.679) and infiltrate (p = 0.755) than in the control group. Direct microscopy, corneal culture, and chop corneal tissue culture were still positive in most of the rabbits from all groups. Histopathological examination showed an increase of inflammatory cells after treatment in all groups, especially in rabbits which were inoculated with A. fumigatus spores in both eyes.  CONCLUSIONS An adjuvant combination of intrastromal and intracameral VCZ showed a tendency of better clinical response for A. fumigatus-induced moderate fungal keratitis in rabbits.
