This research aimed to determine the effect of willow (Salix tetrasperma Roxb) tree bark extract on histopathological changes of liver of rat (Rattus novergicus) infected with Trypanosoma evansi. Liver of 25 male rat, Wistar strain, were used in this study and all rat were fed with commercial feed ad libitum. This research used completely randomized design (CRD) with 5 treatments, each treatment consisted of 5 replicates. Treatment I was negative control group without any treatment, treatment II were only infected with 103 T. evansi, treatment III, IV, and V were infected with 103 T. evansi and treated with willow tree bark extract with the dose of 30, 45, and 60 mg/kg bw, respectively. The administration of willow tree bark extract was carried out for 3 consecutive days orally using a stomach tube. All rats were sacrificed and necropsied then liver were collected for histopathological examination. Percentage of histophatological changes found in hepatocytes of rat infected with T. evansi after the administration of willow tree bark extract in group P1, P2, P3, P4, and P5 were: normal hepatocytes 96.28%; 0.00%; 8.06%; 40.61%; and 0.00%; hydropic degeneration 0.00%, 44.98%, 58.00%, 38.29%, and 35.04%; fatty degeneration 0.00%, 0.00%, 0.00%, 0.00%, and 8.76%; necrosis 3.72%, 55.02%, 33.94%, 21.10%, and 56.20, respectively. In conclusion, the administration of willow tree bark extract is able to protect rat’s liver from T. evansi infection and the dose of 45 mg/kg bw is more effective than 30 mg/kg bw but the dose of 60 mg/kg bw of willow tree bark extract worsen the liver damage.Key words: histopathology, liver, T. evansi, willow

Purpose: To investigate the neuroprotective and memory-boosting properties of ethanol extract of Vateria indica bark on scopolamine-mediated defects in learning and memory in young mice. Methods: The ethanol extract of V. indica bark was prepared via Soxhlet extraction and subjected to qualitative and quantitative phytochemical assessment. The acute toxicity of the extract was also evaluated in mice. Six groups of 3-month-old Swiss albino mice (6 per group) were used: normal control, negative control, piracetam group, 250 mg/kg V. indica extract alone group, 500 mg/kg V. indica extract alone group, 250 mg/kg V. indica extract + scopolamine group and 500 mg/kg V. indica extract + scopolamine group. The mice were pretreated with piracetam (standard nootropic drug) or varied doses of the extract for 14 days prior to induction of amnesia. With the exception of normal control group, amnesia induction using scopolamine (3 mg/kg) i.p. on day 14 at 1½ h after the last extract dose. Mice in normal and negative control groups received 0.5 % tragacanth orally at a dose of 10 mL/kg. Cognitive deficit was assessed using elevated plus maze (EPM), step-down avoidance, and Morris water maze (MWM) tests. Results: Qualitative phytochemical screening of V. indica bark extract showed flavonoids, phenolics, glycosides, tannins, carbohydrate, saponins and steroids. The total phenol and total flavonoid contents were 580.96 ± 0.95 mg GAE/g extract and 66.89 ± 0.56 mg RE/g extract, respectively. The mice tolerated the extract up to 5000 mg/kg bwt. They all survived during and after the acute toxicity study and no significant changes in appearance or general behavior were noticed. The extract significantly enhanced learning and memory, and improved spatial recognition in scopolamine-induced amnesic mice (p < 0.05). Acetylcholinesterase (AChE) activity and levels of dopamine and noradrenaline were markedly higher in negative control mice than in normal control, but were significantly reduced after pretreatment with ethanol extract of V. indica bark (p < 0.05). The results of histopathological examination provided evidence in support of the protective effect of the extract on hippocampal and cortical neurons. Conclusion: Pretreatment with ethanol extract of V. indica bark confers neuroprotection and enhances memory in young amnesic mice. Therefore, the extract of the plant can potentially be develpoed for the management of degenerative brain conditions.

Background and Aim: Although existing research confirms the antiparasitic effect of the Malacca plant against Plasmodium, its effect on the liver, one of the target organs of Plasmodium has not been investigated. Therefore, this study was conducted to explore the potential of the ethanolic extract of Malacca (Phyllanthus emblica) leaves in preventing liver damage in mice (Mus musculus) caused by Plasmodium berghei infection. Materials and Methods: This study was conducted using the livers of 18 mice fixed in 10% neutral-buffered formalin. A completely randomized design with a unidirectional pattern comprising six treatments was used in this study, with each treatment consisting of three replications. Treatment 0 was the negative control group infected with P. berghei, treatment 1 was the positive control group infected with P. berghei followed by chloroquine administration at a dose of 5 mg/kg BW, and treatments 2, 3, 4, and 5 were groups infected with P. berghei and administered Malacca leaf ethanolic extracts at doses of 100, 300, 600, and 1200 mg/kg BW, respectively. The extracts were administered orally using a gastric tube for 4 consecutive days. Mice were sacrificed on the 7th day and livers were collected for histopathological examination. Results: Histopathological examination of the livers of mice infected with P. berghei demonstrated the presence of hemosiderin, hydropic degeneration, fat degeneration, necrosis, and megalocytosis. However, all these histopathological changes were reduced in the livers of P. berghei-infected mice treated with various doses of Malacca leaf ethanolic extract. The differences between the treatments were found be statistically significant (p<0.05). Conclusion: Ethanolic extract of Malacca leaves has the potential to protect against liver damage in mice infected with P. berghei. The dose of 600 mg/kg BW was found to be the most effective compared with the doses of 100, 300, and 1200 mg/kg BW.

This research was aimed to study histopathology of rat kidney infected with Trypanosoma evansi after administration of sernai leaves extract (Wedelia bifolora). The samples used were kidneys of 25 male rats strain Wistar which were equally divided into 5 treatment groups. Group P1 was uninfected and untreated control, group P2 was infected with 1x103 T. evansi but not sernai leaves extract, rats from groups P3, P4, and P5 were infected with 1x103 T. evansi and given sernai leaves extract with the dose of 30 mg/kg bw, 45 mg/kg bw, and 60 mg/kg bw respectively. The sernai extract was administered orally using a stomach tube for 3 consecutive days. The next day after last treatment, all rats were sacrificed and necropsied. Kidneys were collected for histopathological examination such as degeneration and necrosis of tubules cells, convoluted contortus duct lumen, and adhesion and atrophy of glomerulus. Sernai leaves extract with the dose of 45 mg/kg bw was the most effective dose to prevent kidney damage due to T. evansi infection.

This is an experimental trial to prepare a vaccine from gamma-irradiated Giardia lamblia which is evaluated in experimental animals. The study was conducted from December 2015 to April 2016. The field survey of the parasite was conducted from those patients attending the laboratories of the Alawi Children's Hospital in Rusafa and the Al-Yarmouk Teaching Hospital in Karkh, through which 1250 stool samples of different age groups were examined. Five groups of mice were used in the study; the first was injected with normal saline and considered as a negative control group, the second was injected with cystic form of non-irradiated Giardia lamblia and considered as a positive control group, whereas the other three groups were injected with gamma irradiated Giardia lamblia at three different doses 10, 15 and 25 rad respectively. Giardia lamblia was primarily cultivated in liver infusion agar for ten days to obtain the active phase. On the sixth day, the cystic phase was purified and standardized to be used in the infection of mice with or without the exposure of gamma rays. Mice showed high sensitivity to parasitic infestation, in the gamma non-irradiated and the irradiated with gamma 10 rad, and 15 rad irradiated groups which was 100%. The results expressed an excystation process of the depleted phases and the release of the feeder phases. The results of the three irradiated groups consisted of histopathological changes of the small, and the rectum by dissection after two weeks of infection, with intestine amputation lesions, as well as ulceration and inflammation of the inflammatory cells represented in small numbers of neutrophil, lymphocytes, and eosinophils. The presence of ulceration and fall of epithelial cells in the intestinal cavity has been shown, and different forms of the parasite have been observed. Mice which was injected with irradiated G lamblia at high dose (25 rad), not show and sensitivity to the challenge infection and no excystation of thy parasite had been done. After 2 wreaks, a comparison was achieved between all study groups in which no histopathological changes were noticed in the mice irradiated with dose of25 rad. After another two weeks, a challenge dose was given (un-attenuated G lamblia) and mice were dissected after another two weeks, no changes on the level of histopathology of intestinal tissue were noticed the results suggested that mice acquire an immunity against the parasite infection.

The aim of this study was to investigate the dose-related effects of fenitrothion (FNT) on the liver and kidney. The study was conducted on 8-week-old male Wistar rats that were divided into four groups (three experimental groups and one control group) and were treated orally with different doses (25, 50, 100 mg/kg) of FNT for 28 consecutive days. After treatment, the rats were anesthetized with ether and liver and kidney samples were taken for histological studies. The results showed that the histopathological changes in the liver were mainly represented by parenchymatous degeneration of hepatocytes with mild necrosis, leukocytic infiltration in the portal area, severe congestion, and hemorrhage. These changes were dose dependent. Marked tubular dilation, hydropic degeneration in tubular epithelium, moderate congestion, and hemorrhage in the cortical and medulla part of the kidney were recorded. Histopathologic examination of the liver and kidney indicated a significant injury only in rats receiving 100 mg/kg FNT.

This research was conducted to study the protective effect of bee honey on the 7,12-dimethylbenz(a)anthracene (DMBA)- induced breast cancer in rat model. The study consisted of three groups: honey group, positive control group (PC), and negative control group (NC) to which the carcinogen was not administered. All rats were fed the diet recommended by the American Institute of Nutrition for growing rats (AIN-93G), with addition of honey (50 g/kg diet) to the honey group. All Rats were fed their diets ad libitum on 12 hours dark/light cycle. At the age of 50 days all rats in the honey and PC groups were gavaged once by the carcinogen DMBA with a dose of 80 mg/kg body Wt. After three weeks of carcinogen administration, rats were palpated weekly to detect any tumor growth. After 18 weeks, all rats were sacrificed. The palpable structures and the mammary glands along with associated lymph nodes were removed and fixed in saline formalin and prepared for histopathological examination. The results revealed that the honey group diet significantly (p < 0.05) reduced the incidence rate of mammary cancer, palpable tumor multiplicity, tumor size and weight compared to the PC group. In conclusion, multi floral honey has a protective effect against DMBA- induced mammary cancer in the initiation, promotion, and progression stages of DMBA-induced mammary carcinogenesis. However, further research is needed to reveal the mechanisms that might have contributed to the preventive effect of honey against mammary cancer.
