Objective: The study was carried out to investigate the antidiarrheal activity of ethanolic leaf extract of Eriobotrya japonica (EEJ) using various models of experimental diarrhea.Methods: Antidiarrheal property of EEJ at 100, 200, and 400 mg/kg/bwt was evaluated using castor oil-induced diarrhea, castor oil-induced enteropooling, and gastrointestinal propulsive models of experimental diarrhea in Sprague Dawley rats of both sexes, weighing 200–250 g. Cytotoxicity test of EEJ was performed using brine shrimp bioassay.Results: Toxicity assay of EEJ showed a lethal concentration value of 1225 μg/ml suggesting non-toxicity. EEJ significantly (p<0.05) and dose-dependently (100, 200 and 400 mg/kg/bwt) inhibited castor oil-induced diarrhea by 38.1%, 76.19%, and 100%, respectively, and enteropooling by 28%, 56%, and 88%, respectively, compared with control. Pre-treatment with yohimbine, α2-adrenoceptor blocker significantly reversed the protective effect of EEJ (400 mg/kg) against castor oil-induced diarrhea and against castor oil-induced enteropooling, suggesting the involvement of α2-adrenoceptors in antidiarrheal property of EEJ. Furthermore, EEJ significantly (p<0.05) and dosedependently (100, 200, and 400 mg/Kg/bwt) inhibited gastrointestinal motility by 28%, 62%, and 83.92%, respectively.Conclusion: The study has demonstrated the antidiarrheal potential of ethanolic leaf extract of EEJ, which may be attributable to its dual antisecretory and antimotility activities probably through activation of the sympathetic α2-adrenergic pathway.

<p class="Abstract">In this study the antidiarrheal activity of ethanolic extracts of the leaves of <em>Mikania cordata</em> and <em>Litsea monopetala</em> was evaluated. Diarrhea was induced in mice by oral administration of castor oil (0.5 mL) 30 min after the administration of the extracts. During a 4 hour study the number of diarrheal feces and percentage inhibition of the extracts (200 and 400 mg/kg body weight) was determined. Loperamide (3 mg/kg body weight) served as standard and belonged to the positive control group. The extracts exhibited potent antidiarrheal activity as well as achieved statistically significant p value (p&lt;0.01 and p&lt;0.05) compared to control group. Among the extracts the highest percentage inhibition of defecation (60%) was recorded for leaf extract (400 mg/kg body weight) of <em>L. monopetala</em>. So, the study corroborates the significant antidiarrheal activity of <em>M. cordata</em> and <em>L. monopetala</em> leaf extracts and raises the demand of further sophisticated investigation.</p><p> </p>

Psidium guajava leaves have been proven be antiallergic. From the results of previous research, the ethanol extract of leaves is included in the class materials "Practically Non-Toxic." However, repeated administration may cause toxic effects on body organs, one of which was gaster. Subchronic toxicity had been carried out on 20 male Wistar rats and 20 female wistar albino rats. The test materials were administered orally, every day for 28 days. There are 3 (three) doses of test materials which were 250 mg, 500 mg, and 750 mg/kg BW. Observation of the general toxic effect was performed everyday, then organ sampling was performed on day 29 to examined gaster histology and score using Barthel-Manja methods. The result showed that administration of Psidium guajava leaves extract for 28 days caused physical and behavioral changes, caused soft and mucous feces, and also respiratory disorder. But the extract at dose 250 mg, 500 mg and 750 mg/kg BW did not caused changes on gaster histology profile and score. In conclusion, the extract did not have subchronic toxicity effect on gaster rat, but might caused general toxic effect in the higher dose.

Introduction: Nicotine, a major component of cigarette smoke, alters ovarian function and Ajwa (Phoenix dactylifera) being an antioxidant prevents its toxicity. Aims & Objectives: This experimental study was designed to evaluate protective effect of Ajwa against ovarian toxicity induced by nicotine in adult albino rats. Place and duration of study: The study was conducted in the Department of Anatomy, Federal Postgraduate Medical Institute, Shaikh Zayed Medical Complex, Lahore for duration of 3 months (January 2017-March 2017). Material & Methods: 40 adult female albino rats were divided into four equal groups. 1ml distilled water was given to the rats of control (A) group by gastric intubation, experimental group B was given nicotine injection intraperitoneally (0.1 mg/kg body weight) for 28 days. The rats of experimental group C were given Ajwa fruit extract 1gm/kg body weight daily by gastric intubation, while rats of experimental group D were given 0.1mg/kg body weight nicotine intraperitoneally plus 1gm/kg body weight Ajwa fruit extract by gastric intubation for 28 days. Results: In group B, secondary and Graafian follicles were mostly atrophic, degeneration of granulosa cells, pyknotic nuclei and stromal vacuolization were present. Zona pellucida was torn and irregular. Mean diameters of secondary and Graafian follicles were significantly lower in nicotine group B (p-value<0-001*). Experimental group C revealed normal histological architecture and diameter of ovarian follicles. Near normal restoration of follicular structure was seen in group D. Conclusion: Ajwa fruit extract is counterbalancing for nicotine induced oxidative stress in ovarian follicles of rat, so it may be useful to improve infertility or sub-fertility induced by smoking in females.

Various parts of psidium guajava linn are used in ethnomedicine in controls and treatments of different disorders such as liver, heart, and blood related disorders [11]. This research work investigate qualitative phytochemical composition of ethanol leaf extract of psidium guajava linn and its effect on some hematological parameters in albino rats. Qualitative phytochemical analysis of the extract was performed by standard procedures. A total of 20 adult male albino rats were used, they were randomly placed into 5 groups (A, B, C, D and E) each group containing 4 rats groups A, B, C, and D were administered, via oral intubation, the extract at doses of 200, 400, 600, and 800 mg/kg body weight respectively of the extract for 7 consecutive days. Phytochemical screening shows that the extract was rich in tannins anthraquinones, and flavonoid while alkaloids, saponins, terpenes and glycoside were slightly present. There was a decrease in the average body weight, physical activities, and feed and water intake of the rats in the test groups relative to the control hemoglobin concentrate, total white blood cell and packed cell volume recorded in the groups  administered the extract were significantly (p<0.05) higher than in the control this effect on  the haemotological parameters was found to be dose dependent. The findings of this study suggest that the aqueous extract of the fruit plants may be useful in control and treatment of blood related disorders.  These useful applications may be as a result of the phytochemical present in the extract.

Objective: Doxorubicin (Dox), an anthracycline antibiotic, has been widely used to treat cancer, principally hematological malignancies, and solid tumors. The administration of Dox is a topic of concern in the medical community, as it frequently related to dose-dependent cardiotoxicity. Therefore, the present study was designed to investigate the protective potential of date palm fruit extract on Dox-induced cardiotoxicity.Methods: A total of 40 female albino rats were used in this study and classified into four groups including control, date palm fruit extract, Dox, and treated date palm fruit extract groups.Results: Dox produced a significant increase in creatine kinase-MB and lactate dehydrogenase activities. It also decreased the activities of cardiac glutathione peroxidase and superoxide dismutase but increase levels of cardiac malondialdehyde and also of urinary 8-hydroxy-2-deoxyguanosine. Myocardial toxicity of Dox also appeared in the elevation of serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels, while level of high-density lipoprotein cholesterol decreased. Histopathological studies revealed alteration of cardiac tissue structure by Dox. Treatment with date palm fruit extract restored the aforementioned parameters.Conclusion: Date palm fruit exhibits a cardioprotective influence on the heart tissue against toxicity induced by Dox.
