      During the period between January till December 2012, a total of 119 fish samples were collected and examined from Tigris River between Al-Jadiriya Bridge and Al-Zaafaraniya region in two stations, the first station was located under Al-Jadiriya bridge and the second station was located at Al-Zaafaraniya region before Diayla river in order to know the effects of petroleum hydrocarbons in the tissues of the examined fishes. Fish samples belonged to (16) species (Acanthobrama marmid, Albernus caeruleus, Aspius vorax, Barbua belayewi, B. grypus, B. xanthopterus, Carassius carassius, Carasobarbus luteus, Cyprinion macrostomum, Chondrostomua regium, Gara ruffa, Heteropneustes fossilis, Leuciscus cephalus, Liza abu, Mystus pelusius and Tilapia zillii). The histopathological examination included 44 specimens from the internal and external organs of Chontrostoma regium in order to examine the histopathological changes in some organs like (gills, muscles, kidney, liver and spleen). The results revealed congestion, edema, separating, severe vacuolation and dilation of gill secondary lamella, while muscle samples showed mild hyalinization, infiltration of mononuclear cells and fragmentation. The kidney showed hydropic degeneration, necrosis changes, hyperplastic of melanomacrophages, severe dilation of blood vessels with cellular swelling of renal tubule epithelial lining and depletion of hemopoiotic tissues. Severe dilation and congestion of blood vessels and sinusoid, nucleopleomorphism were noticed with nucleomegalocytic of hepatocytes, hemorrhagic with mineral deposition in hepatic parenchyma. Lymphoid depletion in white pulp and hemopoitic tissues, congestion of red pulp, severe hyperplasia were noticed with dilation of splenic tissues. Water samples from Tigris river were analyzed for measuring the level of petroleum hydrocarbons in water and appeared that the pollution 0.0048 mg/L in Al-Jadiriya station and 0.0674 mg/L in Al-Zaafaraniya station.

A total of 69 fish samples were collected from three stations Tigris River namely (Al-Zaafaraniya, Al-Tagei and Al-Shawaka) at Baghdad city, during the period from January to December 2010). These fishes were belonging to five species which were Barbus luteus, Carassius carassius, Chondrostoma regium, Liza abu and Silurus triostegus. The microscopial examination revealed infection with 39 species of ectoparasites and endoparasites including twenty one from protozoans (five ciliate (E.cyprini, E.dogieli, E.spherica, T.domerguei, T.nigra) and sixteen sporozoa (C.bychowski, Myxidium monstrasum, M.pfeifferi, M.rhodei, Myxobolus bramae, M.cyprini, M.cyprinicola, M.drgajini, M.koi, M.macrocapsulari, M.mulleri, M.oviformis, M.paljanski, M.parvus, M.pfeifferi and M.spherica)),twelve trematodes (nine of them from Monogenea (A.siluri , D.achmerovi , D.anchoratus, D.dulkiti, D.formosus, D.skarjabini, D.varicohrini,D.vasator and Diplozoon pavloviski) three digenea(A.coleostoma,D.commutatum, D.spathacum)), one nematode Rabdicona sp., two acanthocephala (N.cristatus, N.iraqensis), two crustaceans (D.varicoleus, E.sieboldi) and one from fungus I.hoferi. The present study included the histopathological changes which caused by Myxobolus on the site of infection (muscles, kidneys and gills) included muscular disorganization, necrosis, bleeding, hemorrhage and mononuclear cells infiltration, hyperplasia and telengiectasis on the gills secondary lamella. Also, the present study included the histopathological changes on the intestine which infected with Neochinorhynchus iraqinesis included closed of intestinal lumen with parasites section, debris necrosis, severe reduce of intestinal filament and mononuclear cells infiltration.

Lesions of meningoencephalitis were found in 55 per cent of 372 rabbits comprising the laboratory stock regarded as healthy, others with snuffles or dying from different affections while being kept under observation, and still others which were employed for experimental purposes, such as tumor transplantation and Treponema pallidum inoculation. None was injected intracerebrally. The lesions consist in the main of infiltration with mononuclear cells occurring around the blood vessels, in the meninges, in the cortex, and under the ependyma of the lateral ventricles, together with particular focal necrotic areas in the cortex. The incidence of these histopathological changes varies in different series of animals; in those supposedly normal and in rabbits inoculated with a transplantable tumor or with Treponema pallidum material, the percentage of positives was from 40 to 60; in those suffering from miscellaneous diseases, such as pneumonia, septicemia, etc., the percentage was 70, and in rabbits ill with snuffles, as many as 76 per cent were affected. Marked lesions were observed in 47.5 per cent of the total. The histopathological picture observed in these rabbits corresponds to those offered by a number of investigators as evidence of the transmission of certain nervous diseases of man to this animal. The accidental cerebral lesions in the rabbit, of a wide variety, and of frequent occurrence, are to be regarded as existing before any experimental procedure is begun. Their recognition is of the utmost importance in the interpretation of experimental results based on the presence of similar changes in this animal.

SUMMARYMicrofilariae of Brugia malayi were obtained from the peritoneal cavities of infected gerbils and were then injected intravenously into mice. A sub-periodic, nocturnal microfilaraemia was produced. The level of microfilaraemia was proportional to the number of parasites injected, with approximately 1–3% of microfilariae being found in the peripheral circulation. The duration of microfilaraemia was proportional to the number of parasites injected; it subsided by 30 days after injection of 104 microfilariae but was still present at a low level 120 days after injection of 2 × 105 microfilariae. A transient splenomegaly developed after injection of microfilariae. Histopathological examination revealed large numbers of microfilariae free in the lumens of pulmonary small blood vessels and without any accompanying inflammatory reaction. Lesser numbers of microfilariae were seen in the cardiac blood and hepatic and renal blood vessels for the first few days after injection. There was cellular proliferation in the splenic white pulp and vascular congestion of the red pulp. Microfilariae labelled with 51Cr were injected intravenously; 57% of radioactivity was found in the lungs, 8·5% in the liver and 2·9% in the spleen. Mice developed immediate hypersensitivity reactions to B. malayi antigen by 4 weeks after injection, but Arthus and delayed hypersensitivity reactions were not seen at any time. When mice which had been injected 5 months previously were challenged with a 2nd injection of microfilariae, there was an accelerated clearance of parasites over 2 weeks and a marked peripheral blood eosinophilia developed. In contrast with natural infections, in which the continuous production of microfilariae complicates assessment, this model provides a system in which factors controlling the circulation of microfilariae in the bloodstream can be studied independently.

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

Background & Method: The study was conducted in the Department of Medicine Shyam Shah Medical College and Associated Sanjay Gandhi Memorial Hospital, Rewa (M.P). History was followed by a careful clinical examination i.e. cardiovascular, respiratory and gastrointestinal and nervous system. Investigations had done included routine haematological examination, Biochemical analysis, urine examination, ECG, 2 D. Echo & Histopathological examination was done. Result: ST-T changes were most common finding in Aluminium phosphide poisoning in relation to mortality. However hyperkalemia was the most ominous finding associated with 100% mortality, ECG finding in EDB was normal ECG. The most ominous finding was arrhythmia which was associated with 100% mortality. Survivors of ethylene dibromide poisoning echocardiography was normal in 11 (84.61%) followed by pericardial effusion in 2 (15.38%) patients. Conclusion: Noteworthy finding was absence of correlation between cardiovascular involvement, histopathological changes and ECG findings. It was seen that even if ECG showed normal pattern there were significant histopathological changes in heart. Keywords: electro-cardiographic, Aluminium phosphide, ethylene dibromide & poisoning.

Canine parvovirus type 2 (CPV-2) is among the most important and highly contagious pathogens that cause enteric or systemic infections in domestic and nondomestic carnivores. However, the spillover of CPV-2 to noncarnivores is rarely mentioned. Taiwanese pangolins ( Manis pentadactyla pentadactyla) are threatened due to habitat fragmentation and prevalent animal trafficking. Interactions between Taiwanese pangolins, humans, and domestic animals have become more frequent in recent years. However, information about the susceptibility of pangolins to common infectious agents of domestic animals has been lacking. From October 2017 to June 2019, 4 pangolins that were rescued and treated in wildlife rescue centers in central and northern Taiwan presented with gastrointestinal signs. Gross and histopathological examination revealed the main pathologic changes to be necrotic enteritis with involvement of the crypts in all intestinal segments in 2 pangolins. By immunohistochemistry for CPV-2, there was positive labeling of cryptal epithelium throughout the intestine, and immunolabeling was also present in epidermal cells adjacent to a surgical amputation site, and in mononuclear cells in lymphoid tissue. The other 2 pangolins had mild enteritis without crypt involvement, and no immunolabeling was detected. The nucleic acid sequences of polymerase chain reaction (PCR) amplicons from these 4 pangolins were identical to a Chinese CPV-2c strain from domestic dogs. Quantitative PCR revealed a higher ratio of CPV-2 nucleic acid to internal control gene in the 2 pangolins with severe intestinal lesions and positive immunoreactivity. Herein, we present evidence of CPV-2 infections in pangolins.
