SummaryAmong the numerous existing computer-based systems for processing pathological data, none contains sufficient space for encoding data on the basic cytological or histological changes of a certain organ or tissue, upon which the final diagnosis is based.An “analytical record” was constructed listing all the basic changes that can be encountered in the various pathological conditions of the vascular wall. The data collected on the “analytical record” were coded by means of an alphanumeric code and stored in an Apple II 48 K minicomputer.The advantages of this system include the computerization of the data by non-specialized personnel and the possibility to’ quantitatively analyze the histocytopathological parameters used for diagnosis in vascular pathology. This coding system may easily be adapted, with minor modifications, to the histopathological study of other organs and tissues.

Chronic kidney disease is a major global public health problem. The peptide hormones adropin and spexin modulate many physiological functions such as energy balance and glucose, lipid and protein metabolism. However, it is unclear whether these peptides may exert effects on renal damage, tissue remodeling, and inflammatory conditions. In view of the limited information, we aimed to investigate the effect of adropin and spexin on matrix metalloproteinase and inflammatory response genes a rat model of adenine-induced chronic kidney failure. Chronic kidney failure was induced in rats by administering adenine hemisulfate. Renal function was determined in an autoanalyzer. Histopathological modifications were assessed by H&E staining. mRNA expression levels of ALOX 15, COX 1, COX 2, IL-1β, IL-10, IL-17A, IL-18 IL-21, IL-33, KIM-1, MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, MMP-13, NGAL, TGFβ1, TIMP-1, and TNFα in kidney tissue were measured by qPCR. Our results showed an increase of 24-h urine volume, serum creatinine, BUN, and urine protein levels in group with adenine-induced CKF. Adropin and spexin treatments decreased urine protein and 24-h urine volume. Renal damage, TIMP-1, IL-33, and MMP-2 increased after CKF induction, while COX 1, MMP-9, and MMP-13 levels were significantly reduced. Furthermore, KIM-1, TIMP-1, IL-33, and MMP-2 were downregulated by spexin treatment. Renal damage, NGAL, TIMP-1 IL-17A, IL-33, MMP-2, and MMP-3 decreased after adropin treatment, while MMP-13 levels were upregulated. Treatment with adropin+spexin decreased KIM-1, NGAL, TIMP-1, IL-1β, IL-17A, IL-18, IL-33, ALOX 15, COX 1, COX 2, TGFβ1, TNFα, MMP-2, MMP-3, and MMP-7, but increased MMP-13 levels. Our findings revealed that inflammatory response and MMP genes were modulated by adropin and spexin. These peptides may have protective effects on inflammation and chronic kidney damage progression.

The current study was conduct to determine the effects of oral treatment of sweet Almond Suspension (SAS) on induced arthritis by Incomplete Freund’s Adjuvant (IFA).Seventy mice, with close age and weight were used; they were equally divided in to 7 groups (10 mice per group). The first group served as negative control (non infected – non treated (NINTC). The second group was the positive control (infected non treated, (NINTC) the third and fourth groups were those treated with 1.42 or 2.84 g/kg of SAS respectively. The fifth group was treated with voltarin (ITV), while the sixth and seventh groups were treated with the same closes of SAS but before infection (Prophylactic infected groups, PI1, PI2).The size of knee joint, carrageenan test, level of alkaline phosphatase and histopathological changes in the knee joint used as parameters to compare between groups. The results showed that SAS was able to subside signs of arthritis by decreasing the size of knee and decrease the formation of edema which was induced by injection of carrageenan in the paw of the animal, Histopathological study showed that joints of treated groups by SAS had no signs of arthritis. However, there was slight infiltration of netrophile in treatment and prophylactic group.

Abstract Amikacin (AK) is frequently used in the treatment of gram-negative and some gram-positive infections. However, its use is limited due to nephrotoxicity due to the increase in reactive oxygen radicals. The aim of this study was to investigate the role of carvacrol (CAR) against AK-induced nephrotoxicity in rats. Thirty-two Sprague Dawley rats were randomly divided into four groups as control (Vehicle), AK (400 mg/kg), CAR + AK (80 mg/kg CAR + 400 mg/kg AK), and AK + CAR (400 mg/kg AK + 80 mg/kg CAR) groups. AK and CAR were administered via intramuscular and per-oral for 7 days, respectively. Blood and kidney tissue samples were taken at the end of the experiment. Renal function and histopathological changes were compared, and the relevant parameters of oxidative stress and inflammation were detected. Histopathological findings (necrotic changes and dilatation and inflammatory cell infiltration) significantly increased in the AK group compared to the control group. Also, the rats in the AK group lost weight significantly. It was found that CAR treatment before and after AK significantly improved nephrotoxicity histopathologically (p < 0.05). However, this improvement was not detected biochemically. These results show that CAR treatment before and after AK improves nephrotoxicity in the histopathological level.

Abstract Considering that the involvement of reactive oxygen species (ROS) has been implicated in the toxicity of various pesticides, this study was designed to study the ameliorative effect of Vitamin E (100 mg/kg body weight) on mice (25 - 30 mg) treated with diazinon (32.5 or 16.25 mg/kg body weight) organophosphate insecticide for 14 days. Subchronic DZN exposure and the protective effects of vitamins E (vitE) were evaluated for their effects on haematological indices, the enzymes concerning liver damage [plasma alanine aminotransferase (ALT), aspartate aminotaransferase (AST), alkaline phosphatise (AIP), and some parameters of kidney function (urea and creatinine) in mice. Additionally, the histopathological changes in liver and kidney tissue were examined. The high dose of diazinon (DZNH) decreased the body weight significantly at the end of experiment. Additionally, the liver and kidney were examines for histopathological changes. The high dose of diazinon decreased body weight significantly. Moreover, there was a statistically significant decrease in haemoglobin (Hb), red blood cell (RBC) and hematocrit (Hct) in diazinon-treated mice compared to controls. This decrease was partially remedied in the diazinon-treated group that also received vitE. Damage in the liver and kidney tissues was also evident as elevated plasma ALT, AST, ALP, urea and creatinine. VitE partially counteracts the toxic effect of DZN and repairs tissue damage in the liver and kidney, especially when supplemented to 1/4 LD50 intoxicated animals. Histopathological changes in liver and kidney were observed only in 32.5 mg/kg DZN given group. These results suggest that the effects of DZN are dose dependent. No pathological findings were observed in vitE + DZN treated groups. According to the present study, we conclude that vitE can reduce the detrimental impacts of diazinon on haematological indicies, as well as liver and kidney function.

Cyclosporine is considered one of the common worldwide immunosuppressive drugs that are used for allograft rejection prevention. However, articles that address adverse effects of cyclosporine use on the vital organs such as lung are still few. This study aims to investigate pulmonary toxic effect of cyclosporine in rats by assessment of pulmonary histopathological changes using light and electron microscope examination. Sixty male adult albino rats were divided into three groups; each group consists of twenty rats. The first received physiological saline while the second and third groups received 25 and 40 mg/kg/day of cyclosporine, respectively, by gastric gavage for forty-five days. Cyclosporine reduced the lung and body weight with shrinkage or pyknotic nucleus of pneumocyte type II, degeneration of alveoli and interalveolar septum beside microvilli on the alveolar surface, emphysema, inflammatory cellular infiltration, pulmonary blood vessels congestion, and increase of fibrous tissues in the interstitial tissues and around alveoli with negative Periodic Acid-Schiff staining. Prolonged use of cyclosporine induced pulmonary ultrastructural and histopathological changes with the lung and body weight reduction depending on its dose.

SummaryCathaemasia hians is an obligate trematode parasite of Black storks that are on the List of protected birds in Europe. In the present study, adult trematodes were isolated from the Black stork post mortem and morphological study revealed C. hians species. In total, 10 worms were found in the oesophagus and the ventriculus of the bird. Histopathological examination of the tissue samples of oesophagus, proventriculus and ventriculus was performed on paraffin sections using a set of staining procedures. The sporadic lesions were seen in the tela submucosa of oesophagus containing connective tissue mast cells, eosinophils and heterophils and some foci were surrounded by the fibrous tissue. In addition, a few inflammatory nodules had larval-like material inside, probably being of the same species. There were no visible morphological alterations in the epithelial layer of lamina propria mucosae of proventriculus, rich in goblet cells as well as in the tela submucosa. Majority of trematodes were localized in the ventriculus, where the lamina propria mucosae was damaged or disrupted sporadically. In these sites, in the tela submucosa, a various food-originated inorganic/organic material and eggs of C. hians were deposited, stimulating a weak inflammatory response. Nodules containing larvae were not observed in any of ventriculus tissue layers. This study demonstrated, for the first time, infection with adults of C. hians trematode in the Black stork nesting in Slovakia. The presence of larvae and eggs in the tissues of the upper gastrointestinal tract of bird was associated with mild inflammatory response but feeding behaviour of adult worms in the ventriculus probably contributed to the enhanced susceptibility of the lamina propria mucosae to mechanical damage by inorganic material. Although larval stages have not yet been documented in the intermediate hosts in Slovakia, our report indicates that the life cycle of C. hians might occur in Central Europe.

Abstract The effect of naringenin, a flavonoid found in grapefruit, orange, and tomato, on lipid peroxidation and histopathological changes in the liver and kidneys of alloxan-induced diabetic mice were investigated. Two days after alloxan injection (75 mg kg−1, i.v.), naringenin ethanolic solution (0.5 % v/v) was given to mice intraperitoneally (50 mg kg−1 per day) for seven days. Naringenin’s impact on lipid peroxidation was measured by the 2-thiobarbituric acid test and histopathological changes were examined under a light microscope. Naringenin administration resulted in a significant decrease of lipid peroxidation level in liver and kidney tissue, as well as in a decreased number of vacuolated liver cells and degree of vacuolisation. Indications of tissue repair in kidney suggested that amelioration of diabetes-induced renal damage could be achieved over a longer period of time. Findings suggest that naringenin could be considered a dietary supplement in the prevention or treatment of diabetic complications and other diseases connected with oxidative stress, and gives a hope that it could show similar effects in the treatment of diabetes in humans.

Endometritis is commonly caused by pathogenic microorganisms, includingStaphylococcus aureus(S. aureus). Piperine, which is a natural medicine, has shown a variety of biological activities. To explore the effect and mechanism of piperine onS. aureusendometritis, a mouse model ofS. aureusendometritis was successfully established in the present study. Histopathological changes were observed with H&E staining, cytokines were analyzed by ELISA, mRNA was analyzed by qPCR, and proteins were detected by western blot. The results showed that piperine could significantly alleviate inflammatory injury inS. aureusendometritis. The qPCR and ELISA results showed that piperine effectively reduced theS. aureus-induced overexpression of TNF-α, IL-1β, and IL-6 but increased the expression of IL-10. TheS. aureus-induced inflammation was related to TLR-2 and TLR-4 because the results showed that their expression was increased inS. aureusinfection but then decreased with piperine treatment. To further confirm that piperine caused an anti-inflammatory response by targeting NF-κB and MAPKs, the expression of I-κB, p65, p38, ERK, and JNK was measured. The phosphorylation of I-κB, p65, p38, ERK, and JNK was inhibited by piperine in a dose-dependent manner. All of the results indicated that piperine may be a potential anti-inflammatory drug both in endometritis and in otherS. aureus-induced diseases.
