Abstract Introduction: Many antioxidant agents have been studied for prevention and treatment of the kidney stone disease in animals and humans. Parkinsonia aculeate (P. aculeate) has a wide range of pharmacological and biological activities, particularly antioxidant properties. The goal of this research was to investigate the anti-urolithiatic effect of P. aculeate extract on ethylene glycol induced renal calculi.Materials and methods: A total of 42 male Wistar rats were randomly divided into six equal groups with seven rats in each group: Group A served as healthy control group and received distilled water for 30 days. Group B served as ethylene glycol control group and received 1% v/v ethylene glycol in distilled water for 30 days. Group C, D, and E animals (preventive groups) concurrently received 1% v/v ethylene glycol in distilled water along with extract of P. aculeata orally for 30 days in doses of 100 mg/kg (low dose), 200 mg/kg (moderate dose), and 300 mg/kg (high dose), respectively. Group F (treatment groups) received 1% v/v ethylene glycol in distilled water for the first 30 days along with extract of P. aculeata 300 mg/kg orally from 15th to 30th days. At the end of study period, 24-hour urine and serum samples were collected and analyzed. All rats were sacrificed and both kidneys were removed, weighed and histopathologically evaluated for calcium oxalate crystals.Results: Ethylene glycol significantly decreased serum calcium, urinary levels of creatinine, calcium and uric acid. On the contrary, it significantly increased 24-hour urine volume, kidney weight, and calcium oxalate deposits. The highest number of calcium oxalate crystal depositions were in the high dose preventive group (76.6%), which is statistically significant difference with other groups including ethylene glycol control (70%), low dose preventive (72%), treatment (38%), and moderate dose preventive (42%) groups (P value < 0.05). Administration of extract of P. aculeata significantly reduced the production of calcium oxalate stones in moderate dose preventive and treatment group. However, P. Aculeata extract was not effective in reducing the formation of calcium oxalate stones in low dose and high dose preventive groups. Interestingly, the number of calcium oxalate deposits in the renal tubules of high dose preventive group was significantly more than the ethylene glycol control group.Conclusions: Extract of P. aculeata has preventive and therapeutic effects in ethylene glycol induced renal calculi in Wistar rat. Further studies are necessary to clarify the mechanism underlying this effect.

Objective. The study aimed to determine if Blumea balsamifera inhibits calcium oxalate stone formation in the kidneys through determination of the number of calcium oxalate stones in the renal cortex and the percent mass of calcium oxalate. Methods. Post-test only control group design was used using five treatment groups with placebo as the negative control, potassium citrate as the positive control, and 50%, 100%, and 200% sambong treatment. Urolithiasis was induced through ethylene glycol and ammonium chloride. Each treatment group was administered its corresponding treatment solution once daily for twenty-one days. Histopathologic examination and kidney homogenate analysis were done to determine the degree of deposition of calcium oxalate stones in renal tissues and the oxalate content, respectively. Statistical analyses were performed using one-way ANOVA and post hoc Gabriel's Pairwise Comparisons Test. Results. The 100% sambong treatment group showed the least mean number of stones while the positive control and 50% sambong treatment group exhibited the highest anti-urolithiatic activity in terms of oxalate content of the kidney homogenate. Conclusion. It can be concluded from the study that Blumea balsamifera inhibits calcium oxalate stone formation in the kidneys with the 100% and 50% sambong treatment most effective in decreasing number of stones and oxalate content of the kidney homogenate, respectively.

Copper Poisoning

In this study, the clinical manifestations of copper poisoning and the pathological changes of tissues and organs were observed by copper sulfate. The experimental mice were randomly divided into four groups: control group (0 mg / kg), low dose group (50 mg / kg), medium dose group (100 mg / kg), high dose group (200 mg / kg), 6 rats in each group, the test period was 2 weeks. The results showed that the mortality rate in the high dose group was higher than that in the middle dose group and the low dose group. Pathological observation of high-dose group showed hepatic steatosis and granular degeneration, hepatocyte showed honeycomb appearance, low dose group and middle dose group hepatocyte enlargement, cytoplasm filled with red stained fine particles; low dose group In the renal tubular degeneration, renal tubular epithelial cell swelling, so that the lumen becomes smaller or narrow, interstitial telangiectasia, congestion. In the middle dose group, there were obvious degeneration of the renal tubules, and there were many red dye protein in the lumen. Part of the renal tubular wall cell structure was destroyed. High dose group of renal tubular epithelial necrosis, disintegration, fall off in the lumen. The results show that copper poisoning mainly damage the liver, kidney and other tissues and organs, eventually leading to morbidity and even death.

Background: Monosodium glutamate (MSG) or Aji-no-moto is the common flavouring agent which is inadvertently used in all the packed and ready to use food items. Its use has grabbed the attention with reporting of Chinese restaurant syndrome and many more side effects. This flavouring agent effects almost all the organs of the human body but the statistics regarding its ill effects are very limited, thus no objections are being raised for its use in eatables. In current study we planned to analyse the pathological effects of MSG on the liver of adult albino rats.Methods: The study was conducted on 18 inbred adult albino rats of either sex. The rats of control group (A) received only standard diet with distilled water, low dose test group (B) rats received 0.5 mg/kg of MSG dissolved in distilled water and high dose test group (C) rats received 1.5 mg/kg of MSG dissolved in distilled water per orally for 28 days. After the experimental period, the rats were sacrificed to dissect out the liver tissue which was later subjected to histological processing and tissue sectioning.Results: The liver tissue sections of the control group (A) revealed normal hepatic architecture with central veins located in the centre of the hepatic lobule and portal areas containing portal triad formed by portal venule, hepatic arteriole and bile ductile. On the other hand, the liver sections of low dose group (B) exhibited pathological changes in the form of dilated and congested central vein with sinusoidal dilatation. In high dose group (C), more marked pathological changes seen in group B along with dilatation of the portal vein was also seen.Conclusions: MSG is most widely used food additive whose safe limits for use need to be scrutinized. The current study was planned to access the minimal low dose limit of MSG for use. The observations of the afore mentioned study revealed that even small dose of MSG of 0.5 mg/kg is capable of producing pathological effects in liver which is the main site of metabolism of xenobiotics

Exposure to drugs and toxic chemicals, during late pregnancy, is a common occurrence in childbearing women. Some studies have reported that more than 90% of pregnant women use at least 1 prescription; of this, 60% used more than one. Another study indicated that 80% of the consumed drugs were not prescribed, and of this figure, 95% were “over-the-counter” drugs. Acetaminophen, the safest of all over-the-counter drugs, has been reported to induce fetal liver necrosis in man and animals and to have abortifacient and embryocidal action in mice. This study examines the degree to which acetaminophen affects the neonatal liver and kidney, when a fatty diet is simultaneously fed to the mother during late pregnancy.Timed Swiss Webster female mice were gavaged during late pregnancy (days 16-19) with fat suspended acetaminophen at a high dose, HD = 84.50 mg/kg, and a low dose, LD = 42.25 mg/kg; a control group received fat alone.

Background Evidence begin to accumulate that high-dose sub-lingual immunotherapy (SLIT) is as effective as subcutaneousimmunotherapy (SIT) in the treatment of childhood asthma.Since the capacity of sublingual area is similar whether the doseis high or low, the efficacy of low dose may be important to bestudied.Objective To investigate the efficacy of low-dose sublingual im-munotherapy in the treatment of childhood asthma.Methods Parents signed informed consent prior to enrollment,after having received information about the study. Patients weremoderate asthma aged 6-14 years with disease onset of lessthan 2 years before the commencement of the study and peakexpiratory flow rate (PEFR) variability of more than 15%. Pa-tients were randomly allocated into group A, B, and C whoreceived subcutaneous immunotherapy, low-dose sublingualimmunotherapy, and conventional asthma therapy, respectively.Randomization was stratified into two strata according to agei.e., 6-11 years or 11-14 years. Patients of each stratum wererandomized in block of three for each group. At the end of threemonths, lung function tests were repeated. The primary outcomewas PEFR variability at the end of the study. The study wasapproved by the Ethics Committee of Soetomo HospitalSurabaya.Results Distribution of variants as represented by sex, age,eosinophil count, and total IgE concentration were normal inthe three groups. PEFR variability decreased significantly from16.97+0.81 to 8.50+5.08 and 17.0+0.87 to 8.40+4.72 in groupreceiving SIT and SLIT, respectively (p<0.05), but decreasednot significantly from 17.00+0.83 to 10.82+0.5.41 in control group(p>0.05).Conclusion Low-dose SLIT is as efficacious as SIT in the treat-ment of moderate asthma in children

(1) Background: The endothelial glycocalyx is a primary target during the early phase of sepsis. We previously reported a newly developed recombinant non-fucosylated antithrombin has protective effects in vitro. We further evaluated the effects of this recombinant antithrombin on the glycocalyx damage in an animal model of sepsis. (2) Methods: Following endotoxin injection, in Wistar rats, circulating levels of hyaluronan, syndecan-1 and other biomarkers were evaluated in low-dose or high-dose recombinant antithrombin-treated animals and a control group (n = 7 per group). Leukocyte adhesion and blood flow were evaluated with intravital microscopy. The glycocalyx was also examined using side-stream dark-field imaging. (3) Results: The activation of coagulation was inhibited by recombinant antithrombin, leukocyte adhesion was significantly decreased, and flow was better maintained in the high-dose group (both p < 0.05). Circulating levels of syndecan-1 (p < 0.01, high-dose group) and hyaluronan (p < 0.05, low-dose group; p < 0.01, high-dose group) were significantly reduced by recombinant antithrombin treatment. Increases in lactate and decreases in albumin levels were significantly attenuated in the high-dose group (p < 0.05, respectively). The glycocalyx thickness was reduced over time in control animals, but the derangement was attenuated and microvascular perfusion was better maintained in the high-dose group recombinant antithrombin group (p < 0.05). (4) Conclusions: Recombinant antithrombin maintained vascular integrity and the microcirculation by preserving the glycocalyx in this sepsis model, effects that were more prominent with high-dose therapy.

Background and Aim: Thyroid is one of the endocrine glands, (T3 and T4) play a significant role in the development of prenatal brain and the following stages. The study aimed to evaluate the effect of hypothyroidism on the amount of expression of NT4, NT3, nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) in brain of one-day rat neonates with hypothyroidism.Materials and Methods: In total, 25 mature mice of Albino NMRI race were selected after mating, divided into three group, control, as well as low-dose and high-dose intervention groups. Samples of the control group received pure water during pregnancy, whereas subjects of the intervention group with low and high doses of the medication were administered with 20 mg and 100 mg methimazole powder (dissolved in 100 cc water), respectively. After child delivery, blood samples were obtained from mother mice to determine the level of T3 and T4 in blood serum. Following that, the brain of one-day mice were removed by surgery and assessed to determine the amount of expression of NT4, NT3, NGF and BDNF using the complete kit of RT-PCR.Results: Levels of T4 and T3 in the control group were 28 ug/dl and 1.59 ug/dl, respectively. In the low-dose intervention group, the amounts of the mentioned hormones were 8 ug/dl and 0.85 ug/dl, significantly, indicating a significant reduction in the expression of NT4, NT3, NGF and BDNF genes, compared to the control group. Moreover, T4 and T3 were 6 ug/dl and 0.79 ug/dl in the high-dose group, respectively, conveying a significant decrease in the expression of NT4, NT3, NGF and BDNF genes, compared to the control group (P<0.05).

SynopsisIn 17 benzodiazepine (BDZ) dependent in-patients a CT scan was performed before initiation of withdrawal therapy. The evaluation of the ventricular to brain ratio (VBR) by standardized and computerized measurements revealed significantly higher mean VBRs for both high-and low-dose BDZ-dependent patients compared to the mean VBR of an age- and sex-matched control group. In addition, the mean VBR of high-dose BDZ-dependent patients (N = 8) was significantly higher than the mean VBR of low-dose BDZ-dependent patients (N = 9). This difference could not be accounted for by the age of the patients or duration of BDZ-dependency and, therefore, suggests a dose-dependent effect of BDZs on the enlargement of internal CSF-spaces. On the other hand, higher values for the width of external CSF-spaces were found to be related to increasing age of the patients and duration of BDZ-dependency.

Diminished ovarian reserve (DOR) refers to a decrease in the number and quality of oocytes. Western treatment of DOR does not improve the ovarian reserve fundamentally, and the effect is limited. Gengnianchun recipe (GNC) is a traditional Chinese medicine formula originally applied to treat menopausal syndrome but is also found to be effective in treating clinical DOR patients. Here we aim to examine the effect of GNC in a DOR rat model induced by 4-vinylcyclohexene diepoxide (VCD), a chemical that selectively destroys ovarian small preantral follicles, and further investigate the possible mechanisms. Female SD rats were randomly divided into four groups: control group (C), model group (M), high-dose GNC group (H), and low-dose GNC group (L). Rats in M, H, and L were administered with VCD and normal saline, high-dose GNC, and low-dose GNC separately. Rat ovaries were harvested either to conduct HE staining for follicle count, immunohistochemistry, or western blot. We found that high dose of GNC significantly increased the ovarian index and sustained the number of primordial follicles and primary follicles in VCD treated rats. Moreover, high dose of GNC significantly increased the ovarian protein expression of mouse vasa homologue (MVH), anti-Müllerian hormone (AMH), follicle-stimulating hormone receptor (FSHR), and estrogen receptor β (ERβ) compared with that in the model group. Besides, high-dose GNC significantly increased ovarian AKT phosphorylation and the expression of downstream forkhead box O3 (FOXO3a). Proapoptosis proteins of Bax, cleaved caspase-3, and poly ADP-ribose polymerase (PARP) were significantly decreased after high-dose GNC treatment compared with those in the model group. Taken together, these findings suggest that high-dose GNC could protect ovarian reserve against VCD-induced toxicity via the activation of the AKT signaling pathway and reduced cell apoptosis in SD Rats. This effect could either be induced by the increased FSHR signaling or by the nontranscriptional activation of ERβ, which requires further investigation.
