Staphylococcus aureus is a Gram-positive bacterium that causes inflammation such as mastitis in the breast. Breast mastitis can occur in nursing mothers and requires first aid or initial treatment. Herbal ingredients can be utilized because they are easily obtained and can be prepared by the community themselves. The study aimed to analyze the effectiveness of soursop leaf extract on IL-6 levels in mammae of female rats Sprague dawley induced by S. aureus. The study was divided into four groups consisting of five rats that were induced by S. aureus 2 x 107 CFU/ml. Group I was given 0.5% Na.CMC, Group II gave 45 mg/kgBW cefadroxil antibiotics, group III administered 100 mg / kgBW soursop leaf extract, and group IV administered soursop leaf extract combined with cefadroxil. Each group was given treatment twice a day for 5 days. IL-6 levels were measured on days 3 and 6. The results of this study showed IL-6 levels in group III were 7.50 ± 1.74 pg/ml on the 3rd day, and 4.51 ± 1.47 pg/ml on the 6th day. The results showed there were differences in IL-6 levels in group III (p = 0.037). Soursop leaf extract can be used as a therapy for mastitis caused by S. aureus.

Patients with collapsing glomerulopathy (CG) have marked proteinuria that rapidly progresses to chronic renal failure. In this study, we investigated if the nephropathy produced in a rat model by the injection of serum from CG patients induced alterations in fatty acid (FA) metabolism. Twenty-four female Sprague-Dawley rats were divided into four groups of six rats each: Group I, control rats (C); Group II, rats that received injections of 1 mL of 0.9% NaCl saline solution (SS); Group III, rats injected with 25 mg/mL of serum from healthy subjects (HS); and Group IV, rats injected with 25 mg/mL of serum from CG patients. In all groups, the systolic blood pressure (SBP), proteinuria, creatinine clearance (CC), cholesterol and total FA composition in the kidney and serum were evaluated. The administration of serum from CG patients to rats induced glomerular collapse, proteinuria, reduced CC and elevated SBP (p ≤ 0.01) in comparison with the C, SS and HS rats. The FA composition of the serum of rats that received the CG serum showed an increase in palmitic acid (PA) and a decrease in arachidonic acid (AA) when compared to serum from HS (p ≤ 0.02). In rats receiving the CG serum, there was also a decrease in the AA in the kidney but there was an increase in the PA in the serum and kidney (p ≤ 0.01). These results suggest that the administration of serum from CG patients to rats induces alterations in FA metabolism including changes in PA and in AA, which are precursors for the biosynthesis of the prostaglandins that are involved in the elevation of SBP and in renal injury. These changes may contribute to collapsing glomerulopathy disease.

Abstract Background Staphylococcus aureus (S. aureus) accessory gene regulator (agr) system plays a critical role in staphylococcal pathogenesis. Our study aimed to investigate the relationship between agr group, the genetic background, virulence genes and disease types distribution of S. aureus isolated from different clinical sources among Chinese children.Methods S. aureus strains were isolated from Beijing Children’s hospital from October 2017 to October 2019. Isolates were typed by multilocus sequence typing (MLST), staphylococcal protein A (spa), agr, and staphylococcal cassette chromosome mec (SCCmec) typing (for methicillin-resistant S. aureus [MRSA] isolates). Furthermore, all isolates were tested for the presence of 19 selected virulence genes.Results A total of 191 non-repetitive S. aureus clinical isolates were collected and the agr type I was the most prevalent (84.8%). S. aureus isolates were divided into 33 sequence types (STs), 20 clonal complexes (CCs) and 59 spa types, ST59 (39.8%) and t437 (37.7%) were the predominant types. CC59, CC25, CC22, CC951, CC8, and CC398 isolates possessed agr group I; CC15 isolates harbored agr group II; CC30 strains were characterized as agr group III, and CC121 harbored agr group IV. Of the 19 virulence genes, the tst gene was more prevalent among agr group III compared to other groups (p = 0.006); eta and etb genes were more prevalent among agr group IV than other groups (p = 0.003 and 0.001, respectively); nearly all strains that harbored the lukS/F-PV gene (98.3%) belonged to agr group I (p = 0.004); the frequencies of bbp and ebpS genes belonged to agr group I were statistically lower than that of other groups (p < 0.001). Among 161 diagnoses, the frequency of strains from cellulitis patient harbored agr group III was higher than that of other groups (p = 0.046), and one strain isolated from staphylococcal scalded skin syndrome (SSSS) patient, which was identified as agr type IV (p = 0.021).Conclusions The results indicated that the S. aureus agr type was linked to the genetic background. Besides, a possible relationship between the agr group, several virulence determinants, and specific disease types was observed.

Immunomodulator is a substance that increases or suppresses the immune response through the certain mechanism. The marine sponge Xestospongia sp. has immunomodulatory activity by increasing phagocytic activity. In addition, the phagocytic activity is affected by CD4+ and CD14 cells levels. Thus, this study aims to investigate the effect of Xestopongia sp. extract toward CD4+ and CD14 cells level in model rat. Animals were divided into 4 groups (n=5) and treated for 7 days, as follow: Group I (Ethanolic extract of Xestospongia sp. dose of 300 mg/KgBW); Group II (Ethanolic extract of Xestospongia sp. dose of 400 mg/KgBW); Group III (Phylantus niruri extract); and Group IV (0.5% Na CMC). On day 8, animals were infected with Staphylococcus aureus intraperitoneally. And the blood was collected by cardiac puncture and assayed with ELISA kit CD4 (elabscience®) and ELISA kit CD14 (elabscience®). Ethanolic extract of Xestospongia sp. provided high levels of both CD4+ and CD14 cells (Group II) compared to baseline (Group IV)  (p<0.05). Group I provided similar activity to group III (p>0.05) and Group II provided significant activity with higher levels of CD4+ and CD14 cells compared to group III (p<0.05). In conclusion, both doses of Xestospongia sp. extract provide activity as immunomodulator by increasing CD4+ and CD14 cells levels, yet dose of 400 mg/KgBw provides the higher immunomodulatory activity.

High Oxidative Stress

Cataracts are one of the most causes of blindness in the world. Oxidative stress can form pathological conditions such as cataracts. This oxidative stress ability can be measured by the malondialdehyde (MDA) biomarker. Binahong leaves (Anredera cordifolia (Tenore) Steenis) are native plants from Indonesia that are used to treat various diseases including cataract treatment. Binahong leaf (Anredera cordifolia (Tenore) Steenis) has a high amount of flavonoids and is rich in antioxidants that can be used to treat cataracts. Objective. The purpose of this study was to assess the effect of binahong leaf extract on the levels of MDA in a goat lens with cataract-induced material. Method. As many as possible, 40 goat eye lenses were divided into several groups, namely, group I normal lenses as controls (glucose 5.5 mM), group II lenses were cataract induced with glucose concentration of 55 mM, group III lenses with glucose 55 mM + binahong leaf extract (100 μg/ml), group IV lens with glucose 55 mM + binahong leaf extract (200 μg/ml), and group V lens with glucose 55 mM + quercetin (positive control). Biochemical parameters measured in the lens homogenate are malondialdehyde lens morphology in all groups’ observations and comparisons made. Results. The results of the study found that the lens group with the addition of binahong extract showed more results transparency compared to lens groups induced by glucose concentrations of 55 mM). This shows that the diabetic cataract group experienced high oxidative stress due to the accumulation of sorbitol compounds derived from glucose which caused turbidity in the goat eye lens and increased levels of lens MDA. Binahong levels at concentrations of 100 or 200 can inhibit MDA production. Conclusion. Binahong (Anredera cordifolia (Tenore) Steenis) extract has the ability to inhibit the production of MDA levels. In glucose-induced goat lenses, binahong extract and quercetin show antioxidant and anticataract properties.

Abstract Background Development of drug-induced hepatic damage (DIHD) during chemotherapy is the most common reason for interruption in chemotherapy. This study evaluated the hepatoprotective activity of the ethanolic extract of Tamarindus indica stem bark (EETI) against the induced DIHD in Sprague Dawley rats. Methods The rats were divided into five groups (n=5). Group I, group III, group IV, and group V rats received 1 mL 1% carboxymethyl cellulose, EETI 100 mg/kg body weight (b.wt), EETI 200 mg/kg b.wt, and silymarin 100 mg/kg b.wt, respectively, orally once every day for 28 days. After 1 h–group II, group III, group IV, and group V rats were administered with isoniazid (INH) and rifampicin (RIF) 50 mg/kg b.wt each orally once every day for 28 days. Then, 24 h after the last dosing, blood was withdrawn from the rats and analyzed for liver specific enzymes and biochemical markers. They were examined for histopathology. Results Co-administration of INH and RIF in group II significantly increased alanine transaminase, aspartate transaminase, alkaline phosphatase, lactate dehydrogenase, serum bilirubin, and cholesterol levels while reduced the total protein and albumin levels compared to that of group I. EETI in group III and group IV rats significantly restored the liver specific enzymes and biochemical markers altered due to co-administration of INH and RIF to normal in a dose-dependent manner. EETI 200 mg/kg b.wt showed better protection to liver than EETI 100 mg/kg b.wt and was comparable to silymarin 100 mg/kg b.wt. It was well supported with histopathology of liver tissues. Conclusions EETI possesses hepatoprotective activity against DIHD in rats. It may have a substantial impact on developing clinical strategies to treat patients with hepatic damage.

Objectives: Colistin is a vital antibiotic used in multidrug-resistant infections. Its most important side effect is nephrotoxicity. Colistin is a weak acid. This study aims to evaluate whether urine alkalinization is protective in the nephrotoxicity of colistin. Methods: Twenty-eight male Sprague-Dawley rats were divided into groups. Group I ( n = 4) was injected with intramuscular distilled water twice a day for 7 days. Group II ( n = 8) was injected with 750,000 IU/kg/day colistin for 7 days. Group III ( n = 8) was injected with the same dose of colistin after their urinary pH was ≥7 through the addition of bicarbonate in their drinking water. Group IV ( n = 8) was injected with the same dose of colistin after their urine density fell below 1010 through the addition of NaCl molds in their food and 12.6 mg/L NaCl in their drinking water. Results: According to tubular degenerations (scored 0–5), group I scored 0, group II scored 4.25, group III scored 2, and group IV scored 1.5. In groups III and IV, protection was achieved ( p = 0.001). The bicarbonate group was not superior to the NaCl group ( p = 0.789). In transmission electron microscopy, group III had more microvilli integrity and autophagic vacuoles compared to group IV. Group IV had mitochondrial swelling and cristae lysis. A lower urine density was related to lower tubular scores ( p = 0.001). Conclusions: Colistin was highly nephrotoxic without protection. Light microscopy findings revealed that urinary alkalinization and NaCl hydration were similarly protective. Urine alkalinization further prevents ultrastructural changes as revealed by electron microscopy.

Ethane in alveolar expirate may have its source in organs other than the lung and be transported to the lung for elimination. We determined ethane production rates in rats (group I) ventilated with hydrocarbon-free air (HFA) before and after exsanguination. To determine whether the lung is the source of increased ethane production during exposure to 100% O2, we measured ethane in the expirate of nine exsanguinated, Sprague-Dawley rats (group II) mechanically ventilated with HFA and then with 100% O2. In all nine animals, ethane elimination rates on 100% O2 increased compared with HFA values. In five of the nine rats, HFA ventilation was reinstated after O2 (group III). In all five, ethane elimination fell with HFA ventilation compared with the value on 100%. Six rats with circulation intact were ventilated with HFA and then 100% O2 (group IV). Ethane production rate for group IV animals breathing HFA was not significantly different from the exsanguinated animals in group II while ventilated with HFA. The mean increase in ethane production for the group II animals was not significantly different from the group IV animals. Lung slices from four other rats (group V) were incubated in saline at 37 degrees C with FeCl2 (10 mg) added to enhance free radical formation. Paired lung samples from the same rat were incubated with either HFA or 100% O2. Headspace gas was analyzed chromatographically for ethane at 120 min. Mean ethane in the O2 samples was higher than for HFA. Rat lung tissue is the main source of increased ethane production during 100% O2 exposure.

Partial Correction

Correction of chloride-depletion alkalosis (CDA) may involve renal as well as extrarenal mechanisms. To determine the relative contribution of these mechanisms in a rat model of CDA produced by peritoneal dialysis (PD), we studied six groups of anesthetized Sprague-Dawley rats after PD. Groups II-IV and IIa were subjected to functional bilateral nephrectomy, and groups I and Ia were sham-operated. Groups I, Ia, II, and IIa were infused with isotonic fluid containing 70 mM Cl- and 40 mM HCO3-; the infusate in group III was 140 mM Cl- and in group IV, 70 mM neutral PO4 was substituted for Cl-. Groups I and Ia were infused at 0.5 ml . h-1 X 100 g body wt-1 and groups II, IIa, III, and IV at 0.25 ml . h-1 X 100 g-1. After 3 h of infusion, early partial correction with reciprocal changes in plasma Cl (+6.1 +/- 1.9 mmHg) and total CO2 (-6.0 +/- 0.8 meq/liter) occurred (P less than 0.01) only in group I. Hypokalemia (3.1 +/- 0.1 meq/liter) also occurred only in group I. The responses of groups Ia and IIa studied at 5 h were similar to those of groups I and II. These data suggest that the kidney, and not extrarenal mechanisms, is primarily responsible for the correction of CDA during infusion of chloride.

PURPOSE: To study morphologic and histochemical alterations arising at the ileocystoplasty site. METHODS: Sixteen Wistar female rats were subjected to ileocystoplasty and sacrificed after eight weeks. Material collected was divided into four groups for histological and histochemical studies: Group I (control) - isolated ileum segment removed during ileocystoplasty; Group II - ileoileal anastomosis; Group III - ileovesical anastomosis and Group IV - ileal segment from the neobladder. Histological and histochemical study assessed dysplasia, metaplasia, acute and chronic inflammation, fibrosis, atrophy, hypertrophy, total mucins, sialomucins and sulfomucins. The non-parametric Wilcoxon and Mann-Whitney tests were employed in statistical analysis. RESULTS: None of the groups presented dysplasia. Acute inflammation and atrophy occurred in Groups II, III and IV, not reaching statistical significance. Metaplasia was significant only in Group III (p=0.012). Chronic inflammation, fibrosis and hypertrophy were significant in Groups II, III and IV. There was a significant increase in total mucin content in Group IV (p=0.014) and a reduction in Group III (p=0.016). Increases in sialomucins were observed in samples for Groups III (p=0.003) and IV (p=0.002) along with reduced sulfomucins in samples from Groups III (p=0.013) and IV (p=0.008). CONCLUSION: Ileocystoplasty in female rats caused squamous metaplasia, chronic inflammatory infiltration, fibrosis, hypertrophy, increase in sialomucin content, reduction in sulfomucins, and alterations in total mucin content with statistical significance, as well acute inflammatory infiltration and muscular atrophy with less intensity.

The present study was undertaken to develop a method and to assess the anti-stress activity of poly herbal formulation HAF-I & HAF-II in immobilised stress induced rat model. Acute toxicity study was performed according to OECD guidelines No. 423. Sprague Dawley female rats were observed periodically for the symptoms of toxicity and death within 24 h and at regular intervals for 14 d. In anti-stress study, total 24 female rats were selected and divided into four groups of six animals each. The stress was confirmed by physiological parameters as well as malonaldialdehyde and FOX1 level measured in the blood samples of 18 animals. On the basis of these parameters, treatments were started in group III to group VI animals taken individually dose of 200 mg/kg body weight daily dose per oral administration. Our finding showed that there were significant (P<0.0001) increased MDA, FOX1 and AChE enzyme activities along with decreased (P<0.0001, P<0.001) catalase, glutathione and total thiol antioxidant enzymes levels in stress induced group as compared to control group. After treatment with respective poly-herbal drugs HAF-I & HAF-II in group III to group IV animals, these above parameters were significantly improved in all treated animals after 20 days. Based on above study, it is concluded that these poly herbal formulations are effective for management of stress but comparativly, HAF-I is more effective for the improvement of stress (MDA, FOX1, AChE) levels and anti-oxidant enzyme during stress.
