Deparaffinization is a stage before the staining process to remove/dissolve paraffin so that the absorption of color in tissue preparations is maximized. Deparaffinization is usually carried out using xylol and toluol. Xylol has toxic effects including acute neurotoxicity, heart and kidney damage, hepatotoxicity, fatal blood dyscrasias, skin erythema, dry skin, peeling skin, and also has a carcinogenic effect. The toxicity effect of olive oil is lower than that of xylol. Oils that have non-polar properties can remove the remaining paraffin contained in the tissue. The purpose of this study was to determine the microscopic appearance of the kidney tissue preparations of mice deparaffinized with olive oil on hematoxylin eosin (HE) staining. The type of research used is experimental research which is analyzed with a descriptive approach. The results of the assessment of preparations deparaffinized with xylol in 80 visual fields obtained 100% good preparations and preparations deparaffinized with olive oil in 80 visual fields obtained 0% poor preparations, 11.3% poor preparations, and 88.7% good preparation. So it can be said that better results are found in the microscopic picture of the kidney preparations of mice (Mus musculus) deparaffinized with xylol.

AbstractThe adrenal cortex accumulates lipofuscin granules with age. Lipofuscin accumulation is also seen in adrenocortical tumors associated with Cushing syndrome (CS), particularly those with PRKAR1A mutations, such as in primary pigmented nodular adrenocortical disease (PPNAD). We investigated the presence of lipofuscin in cortisol-producing adenomas (CPAs) responsible for CS with and without the PRKACA (pLeu206Arg) somatic mutation. Ten paraffin-embedded sections of CPAs from cases with overt CS with (n=4) and without (n=6) a PRKACA mutation were microscopically examined through three detection methods, the hematoxylin-Eosin (H & E) staining, the Fontana Masson (FM) staining using light microscopy, and lipofuscin autofluorescence, using confocal laser scanning microscopy (CLSM). Sections were examined quantitatively according to the intensity of the pigmentation, as well as qualitatively based on the total number of granular pigments at all visual fields per tissue slide. Tissues from CPAs were compared to peritumoral adjacent tissues (n=5), to Conn adenomas (n=4), and PPNAD (n=3). CPAs had significantly higher number of lipofuscin-pigment granules compared to peritumoral adrenal tissue and Conn adenomas (46.9±9.5 vs. 3.8±4.8, p=0.0001). The presence of the PRKACA mutation did not increase the chances of pigmentation in the form of lipofuscin granules within CPAs associated with CS. Thus, all CPAs leading to CS accumulate lipofuscin, which presents like pigmentation sometimes seen macroscopically but always detected microscopically. PPNAD caused by PRKAR1A mutations is the best known adrenal lesion leading to CS associated with intense lipofuscin pigmentation and this was confirmed here; CPAs harboring PRKACA mutations did not have statistically significantly more pigmentation than CPAs without mutation, but a larger study might have shown a difference.

BackgroundHypotension, increased production of reactive oxygen species, and inflammation are all observed in experimental models of sepsis induced by lipopolysaccharide (LPS).PurposeThe aim of this study was to evaluate the effects of an ethanolic extract of Brazilian olive leaf (Ex), Brazilian olive oil (Olv), Ex + Olv (ExOlv), and palm oil (Pal) in comparison to the effects of omega-3 fish oil (Omg) in a rat model of sepsis-induced acute kidney injury.MaterialsWistar rats were divided into seven groups (seven per group), which were either untreated (control) or treated with LPS, LPS + Ex, LPS + ExOlv, LPS + Olv, LPS + Omg, or LPS + Pal.ResultsLower values of creatinine clearance and blood pressure were observed in the LPS-treated group, and these values were not affected by Ex, Olv, ExOlv, Pal, or Omg treatment. Mortality rates were significantly lower in rats exposed to LPS when they were also treated with Ex, ExOlv, Olv, Pal, or Omg. These treatments also decreased oxidative stress and inflammation (Tumor necrosis factor alpha, interleukin-1 beta) and increased interleukin-10 levels and cell proliferation, which were associated with decreased apoptosis in kidney tissue.ConclusionEx and Pal treatments were beneficial in septic rats, since they increased survival rate and did not aggravate inflammation. However, the most effective treatments for septic rats were Olv in comparison to Omg. These natural food substances could enable the development of effective therapeutic interventions to sepsis.

Due to great hazard effects of antibiotic the following study aimed to investigate the adverse effect of cefotaxime in biochemical, oxidative status and histological examination of Liver and kidney tissue as well as the protective effect of olive oil. Twenty four male Wister albino rats were randomly divided into main four groups including: - G (1): Served as control group and it includes six rats, they were administrated 0.5ml of saline orally for 14 consecutive days. G (2): it includes six rats, they were administered 5ml/kg olive oil orally for 14 consecutive days. G (3): it includes six rats, they were administrated 90mg/kg body weight/twice daily of cefotaxime intramuscular for 14 consecutive days. G (4): it includes six rats, they were administered 5ml/kg olive oil orally concurrently with 90mg/kg body weight/twice daily of cefotaxime. Results revealed that cefotaxime induced significant increases in liver and kidney function parameters including AST, ALT, ALP. creatinine, and urea as well as decrease in albumin and total protein level. Moreover, marked an increase in malondialdehyde (MDA) and decreases in glutathione (GSH) and catalase (CAT) levels. that indicate oxidative stress levels expression in the hepatic and renal tissues following cefotaxime administration. On the beneficial side oral administration of olive oil at the dose 5ml/kg for 14 days significantly mitigate theses toxic effects. So it is concluded that olive oil has great hepatorenal antioxidant effect.

Ligusticum chuanxiong can relieve the degree of renal fibrosis. However, the specific mechanism of Ligusticum chuanxiong to improve renal fibrosis is not yet clear. A unilateral ureteral obstruction was used to construct a rat renal fibrosis model. The rats were treated with 20 mg/kg and 40 mg/kg of Ligusticum chuanxiong. Four weeks after treatment, blood was collected from the rats, and the rats were sacrificed. Blood urea nitrogen (BUN), serum creatinine (Scr), kidney tissue malondialdehyde (MDA), and superoxide dismutase (SOD) levels were detected. Hematoxylin–eosin staining was used to observe the pathological rat kidney changes. The renal tissue smooth muscle actin (α-SMA) was detected by immunohistochemistry. Nrf2 and HO-1 levels were determined by PCR using nano-magnetic beads. The results showed BUN, Scr, and MDA levels reduced, while SOD levels were elevated in Ligusticum chuanxiong-treated rats, compared to model rats (P < 0.05). These effects were more dramatic in Ligusticum chuanxiong high dose (HD) rats compared to Ligusticum chuanxiong low dose (LD) rats. Additionally, Nrf2 and HO-1 levels were elevated in Ligusticum chuanxiong-treated rats (P < 0.05). These effects were also more dramatic in HD rats compared to LD rats. These findings indicated that Ligusticum chuanxiong early administration can reduce renal fibrosis in rats by stimulating the Nrf2/HO-1 pathway.

This study investigated the protective effect of vitamin D against carbon tetrachloride (CCl4)-induced nephrotoxicity in rats. Adult male Wistar albino rats were divided into four groups ((A) control; (B) 10-week exposure to CCl4; (C) 10-week exposure to CCl4 + vitamin D treatment; and (D) 10-week exposure to CCl4 + 12 weeks of vitamin D treatment). The CCl4 dose (1.5 ml kg−1) was injected subcutaneously twice a week, while the 0.5 mg kg−1 dose of vitamin D was administered intraperitoneally every day, as appropriate for each group. Whole animal and kidney weights as well as serum urea, creatinine, and glucose levels were measured. Kidney tissue sections were stained with hematoxylin–eosin, Masson’s trichrome, and periodic acid–Schiff. Tubular and glomerular degeneration were detected in the kidney tissues of CCl4-treated rats, together with dilatation and vacuolization within the tubules and hemorrhage in the intertubular region. In the kidney glomeruli; congestion, atrophy, and adhesion to parietal layer were observed. Tissue disorganization and aggregation of Bowman’s capsules were noted. Mononuclear cell infiltration was observed between the glomeruli and the tubules. In contrast, the kidney sections and functional parameters of vitamin D-treated rats were similar to the controls, suggesting that vitamin D treatment is able to reduce renal damage.


Introduction: Nephrotic syndrome is characterized by massive proteinuria due to leakage of glomerular basal membrane, and subsequent process in tubular and interstitial tissue. It should be elucidated whether the severity of histopathological lesions in compartments of kidney tissue play a role and whether lesion in those compartments associated one to another. Aim: The study aims to correlate severity histopathologic lesions among compartments in kidney tissue. Method: All patients with nephrotic syndrome were biopsied and the cores were stained with Hematoxylin-Eosin, PAS, Masson’s Trichrome to look at glomerular, tubular, interstitial and vascular involvements. Glomerular abnormalities including mesangial hypercellularity, endocapillary hypercellularity, membranous; tubular, interstitial, and vascular severities were scored according to type, activity, severity and distribution in histopathologic features. Results: This study included 46 patients consisted of 16 (34.8%) males and 30 (65.2%) females, aged 26 ± 10 years, SBP 121.7 ± 13.10 and DBP 78.21 ± 7.80 mmHg, diagnosed with 14 lupus and 32 non-lupus nephrotic syndrome. Histopathologic abnormalities showed glomerular index was 4.26 ± 2.34, tubular index was 3.09 ± 1.90, interstitial index was 3.02 ± 1.48, vascular index was 0-3, pathologic index was 10.56 ± 4.54. There was significant correlation of severity index between interstitial and glomerular lesions (R=0.49, P=0.001), and between interstitial and tubular lesions (R=0.45, P=0.002). However, there were no significant correlations of severity index between interstitial and vascular lesions, and glomerular and tubular lesions. Conclusion: There are significant correlations of severity index between interstitial with glomerular and tubular lesions. It may implicate that histopathological process in interstitial tissue plays a central role in the pathogenesis of proteinuria in nephrotic syndrome.

Background: Today, people around the world have resorted to herbal medicine, due to the increase in antibiotic resistance and the side effects of synthetic drugs. Methods: Our research focused on the in vivo antifungal activity of three ointments formulated on the basis of methanolic extract of Citrus aurantium peel, ethanolic extract of the aerial part of Artemisia herba alba asso, and essential oil of Artemisia herba alba asso. Wistar rats were made immunosuppressed by Dexamethazone and Tetracycline. Three strains of Candida albicans, S1, S2 and S3 were inoculated. The fungal load of the area tested, the weight of the rats, as well as the macroscopic and microscopic appearance of the skins were determined. Results: Cutaneous candidiasis was manifested as red, thick, scabbed lesions, mostly located on the infected area of the animals. Microscopic observation of histological skin sections of animals infected and treated with the ointments, P1, P2 and P3 showed a well-preserved architecture of the skin. Erythema, edema, ulceration, erosion were seen in the skin of animals receiving placebo or Nystatin. The P3 ointment exerted a very powerful antifungal effect against especially the strain S1 compared to the other ointments (log 3.07±0.006 CFU/ml). The weight was regained significantly in the groups of animals receiving the ointments and a regression of growth was observed in the untreated animals and those treated by Nystatin and placebo. Conclusion: The EAH and MCP ointment and the essential oil of Artemisia developed, allowed to retain their significant antifungal activity against Candida.

Fixation is used to maintain tissue structure in its original form “life-like state” and can protect proteins and tissue components from degeneration. The solution commonly used is 10% NBF. Formaldehyde is chemical substance that is toxic and not environmentally friendly, several studies have shown alternative substitutes fixation, one of which is the honey solution. The study of Mohammed et al (2020) fixated tissue with honey 10% and 20% shown good coloring properties and similar clarity to fixated with formalin 10%. Honey has acidic and dehydrating properties allow most microorganisms to be killed so that tissues will last for a long time. The research objective is to findout the description of microscopic of mice (Mus musculus) kidney tissue which were fixation using 10% honey solution for 24 hours. The research is included in qualitative descriptive research. The research design used was a non-eksperimental with a purposive sampling study approach. The sample used was 32 preparation with total of microscopic overview is 160. Microscopic image of mice (Mus musculus) kidney tissue fixed using 10% honey solution for 24 hours in 80 visual fields were 12.5% of the preparations is not good and 87.5% is good preparations. The microscopic image of mice (Mus musculus) kidney tissue fixed using 10% NBF is better than of the microscopic image of mice (Mus musculus) kidney tissue fixed with 10% honey for 24 hours.

Tissue from a non-functional kidney affected with chronic membranous glomerulosclerosis was removed at time of trnasplantation. Recipient kidney tissue and donor kidney tissue were simultaneously fixed for electron microscopy. Primary fixation was in phosphate buffered gluteraldehyde followed by infiltration in 20 and then 40% glycerol. The tissues were frozen in liquid Freon and finally in liquid nitrogen. Fracturing and replication of the etched surface was carried out in a Denton freeze-etch device. The etched surface was coated with platinum followed by carbon. These replicas were cleaned in a 50% solution of sodium hypochlorite and mounted on 400 mesh copper grids. They were examined in an Siemens Elmiskop IA. The pictures suggested that the diseased kidney had heavy deposits of an unknown substance which might account for its inoperative state at the time of surgery. Such deposits were not as apparent in light microscopy or in the standard fixation methods used for EM. This might have been due to some extraction process which removed such granular material in the dehydration steps.
