Cream<span style="text-decoration: line-through;">s </span>and ointment<span style="text-decoration: line-through;">s</span> are topical dosage forms used in the manufacture of drugs. Topical anti-inflammatory drug is a solution to problems of gastrointestinal side effects caused by taking nonsteroidal anti-inflammatory drug orally. The compound 2,5-bis (4-nitrobenzilidine) cyclopentanone is an analog of curcumin which has better anti-inflammatory activity than curcumin. This study aimed to determine the antiinflammatory effect of cream and ointment from 2,5-bis (4-nitrobenzilidine) cyclopentanoneagainst edema in mice induced by formalin. This research were experimental randomized complete design using a single factor. Twenty mice were divided into 4 groups: group I were given a cream base, the group II were given ointment base, group III were given cream compound 0.25% and group IV were given ointment compound 0.25%. The data were processed into AUC values and the percentage of anti-inflammatory effectwere calculated. Results were analyzed using ANOVA and T-test statistics. The results showed that between the dosage form had statistically difference of anti-inflammatory effect (p&lt;0.05). The ointmentshowed a greater value of antiinflammatory activity rather than cream.

The present study was carried out to study coumestan derivative wedelolactone in Indomethacin-induced enterocolitis in rats. Wistar rats were randomly divided into three groups containing six animals per group. Group I served as normal control. Group II, Group III & Group IV receive 7.5 mg/kg, s.c, indomethacin on two consecutive days. Group III and Group IV have received a wedelolactone dose of 50 mg/kg, and 100 mg/kg per oral, respectively, for 14 days after the induction with indomethacin. The protective effect was measured based on intestinal parameters of the disease activity index, colitis score, myeloperoxidase (MPO) activity in the colon. The inflammation biomarkers were quantified by ELISA in the rat colon. Further, activity was ascertained by histopathology. Pro-inflammatory functions IL-1a, IL-1b, IL-2, TNF, INFγ, STAT3, and CCL-5 play an important role in the variation of the intestinal immune system. Wedelolactone showed significantly decreased Disease activity index, Colitis score, Myeoloperoxidase activity. Expression of pro-inflammatory was increased in indomethacin-induced groups and was significantly suppressed in animals administered with wedelolactone at 50 mg/kg & 100 mg/kg dose (p<0.01 & p<0.001). Histological reports also revealed that treated groups have comparatively less damage than that of the induced groups. We concluded that wedelolactone showed an anti-inflammatory effect by downregulation of the IL-6/STAT3 inflammatory signaling pathway and the equilibrium production of pro-inflammatory cytokines.

This research aimed to find out if the guava extract has an anti-inflammatory effects compared with diclofenac. This was an experimental study using 30-tails Wistar strain, which is divided into 6 groups that every 1 hour later induced lambda-carrageenan. Group I and IV are given ethanolic extract of cashew leaf 300 mg/kg BW. Group II and V were given cellulose (CMC) 1% as a control. Group III and VI were given diclofenac 4.5 mg/kg of BW. Edema volume from hour 1 to 6 and MDA levels of foot tissue in the hour 6 were measured in group I, II, III. Hyperalgesia was measured in group IV, V and VI. All research results were statistically tested with ANOVA test followed by the Newman Keuls test. Ethanolic extract of cashew leaf 300 mg/kg BW inhibited the formation of edema volume, preventing hyperalgesia significantly (P &lt; 0.05) compared to a group of control and diclofenac. Measurement of MDA levels between groups with ethanolic extract of cashew leaf, control, and diclofenac was not significantly different (P &gt; 0.05). Ethanolic extract of cashew leaf has an anti-inflammatory effect based on inhibition of edema volume, hyperalgesia.

Smokers have high plaque accumulation that initiates gingival inflammation and progresses to periodontitis. Thus, oral hygiene to control microbial plaque formation is an effective method of preventing gingivitis. Medicinal plants such as Moringa oleifera Lam. (MO) and Cyanthillium cinereum (Less.) H. Rob. (CC) have an anti-inflammatory effect that might improve oral health in smokers. This study evaluated the effect of MO leaf and CC extracts using MO lozenges and a combination of MO + CC lozenges on oral inflammation and gingivitis in volunteer smokers. Lozenges consisting of MO and CC extracts were developed and studied in vivo. The results showed that lozenges significantly reduced oral inflammation and gingivitis in volunteers. The gingival index (GI) of group III (MO + CC lozenges) significantly decreased, while the percentage decrease of oral inflammation in group II (MO lozenges) was significantly higher than the other groups. The percentage decrease of GI values in group II (MO lozenges) and group III (MO + CC lozenges) were significantly higher than the placebo group I. Our findings indicated that MO and MO + CC lozenges reduced oral inflammation and gingivitis and showed potential to improve oral health in smokers.

BACKGROUND: The increased strength of zirconia has resulted in its widespread application in clinical dentistry. Nevertheless, the fracture of veneering porcelains remains one of the key reasons of failure. OBJECTIVE: The objective of this study was to compare and analyze the influence of surface conditioning methods on the core-veneer bond strength of zirconia restorations. METHODS: Thirty specimens of zirconia core with sizes 10 × 5 × 5 mm were layered with porcelain of sizes 5 × 3 × 3 mm. On the basis of different surface conditioning methods, four groups were made: Group I: abrasion with airborne alumina particles of 110 μm size, Group II: sandblasting with silica coated alumina particles of 50 μm in size, Group III (modified group): alteration with a coating of zirconia powder prior to sintering, and Group IV (control group): metal core specimens. The shear force of all specimens was tested using a universal testing machine with a 0.5 mm/min crosshead speed. One-way analysis of variance (ANOVA) and Tukey’s post hoc pair wise comparison (p= 0.05) were performed to analyze the shear bond strength. A scanning electron microscope was used to assess the fractured specimens. RESULTS: A statistically significant difference was noted between the groups. The mean value of shear bond strength was 40.25 MPa for Group I, 41.93 MPa for Group II, 48.08 MPa for Group III and 47.01 MPa for Group IV. CONCLUSIONS: The modified zirconia group and control group demonstrated a significantly higher mean bond strength than that of Group I, where airborne particle abrasion was used. The scanning electron microscope showed that cohesive fracture in the porcelain veneers was the main problem of failure in altered zirconia. The modified zirconia specimens in Group III demonstrated significantly improved values of shear bond strength.

AbstractRecent years have seen a rising incidence of male infertility, mostly caused by the decline of sperm quality. The ratio of infertile males to infertile females has escalated from 3:7 in 2013 to current 5:5, which turns male infertility into the research focus of reproductive medicine. This study aimed to clarify the effect of reproductive tract infection by ureaplasma urealyticum (UU) and chlamydia trachomatis (CT) on the DNA integrity and routine semen parameters of infertile males. A retrospective study was performed. A total of 259 infertile males who were treated at the Andrological Laboratory Examination and Reproductive Medicine Center in our hospital were analyzed. qRT-PCR was used to examine the infection status of CT and UU. According to the eligibility criteria, we evaluated the semen parameters and biochemical data of 253 men. Based on the results of PCR, the subjects were divided into four groups: Group I (CT positive, 63 cases), Group II (UU positive, 60 cases), Group III (CT positive and UU positive, 62 cases), and Group IV (no infection, 68 cases). DNA fragmentation index (DFI), sperm count, vitality and morphology, elastase level, seminal plasma malondialdehyde (MDA), and total antioxidant capacity (TAC) were assessed. Compared to Group IV, three groups (Group I, Group II and Group III) showed difference in semen volume, proportion of sperm with normal morphology, sperm motility, progressive motility, and vitality (P < 0.05). Compared to Group IV, Group II and Group III showed difference in DFI (P < 0.05). Compared to Group IV, Group II and Group III showed difference in elastase level (P < 0.05). VCL, VSL, VAP, WOB, ROS, TM, HDS showed differences between groups of abnormal/normal WBC (*P < 0.01).UU infection significantly increased the level of seminal leukocytes only in Group II, but not in the other three groups, indicating that UU is a factor to increase the level of seminal leukocytes. Compared with the normal leukocyte group, there were significant differences in total motility, forward motility and normal sperm ratio between the two groups. The proportion of sperm with abnormal morphology (mostly in the head) showed obvious difference between groups of high and normal seminal leukocytic levels. At the same time, in this study, SCGE and SCD verified that leukocytes could damage sperm DNA by increasing ROS, which ultimately affects male fertility.

Pyrethroid cyhalothrin (PC) is an insecticide that is used worldwide for pest control in agriculture and household use. Samoa extract (SE) is a potent antioxidant protecting cells from oxidative stress. The present study investigates the protective and therapeutic effect of SE on PC-induced changes in sperm quality in male rats. Fifty adult male albino rats were divided into five groups: group I: served as control; group II: received PC i.p. only (6.2 mg/kg b.wt.); group III: received SE only (100 mg/kg b.wt., p.o.) for eight weeks; group IV: received SE as a protective agent daily for eight weeks, then followed by the administration of PC (i.p.) three times a week for two weeks; group V: exposed to PC (i.p.) three times a week for two weeks, then treated with the SE daily for 8 weeks. Results showed that PC caused markedly impaired sperm quality (a count, viability, motility, and abnormality). Compared to PC-treated animals, SE in the protective group markedly restored the alteration of sperm indices. However, SE in the curative group was found to be less effective in restoring PC-induced alterations. In conclusion, the data of this study revealed that the SE as a protective agent is more effective than as a therapeutic agent. Keywords: Samoa; Pyrethroid; Sperm quality; Rat

We evaluated the dose-response relationship between the plasma amino acid (AA) concentration and renal hemodynamics in eight normal subjects. After an overnight fast, a balanced 10% AA solution was infused for 180 min at five separate infusion rates: 0.5 (group I), 1.0 (group II), 2.0 (group III), 4.0 (group IV), and 6.0 (group V) ml.kg-1.min-1 on separate days. Basal plasma AA concentration was 1.87 +/- 0.1 mmol/l and increased to 2.26 +/- 0.1 (group I), 2.66 +/- 0.2 (group II), 3.79 +/- 0.5 (group III), 5.81 +/- 0.4 (group IV), and 7.41 +/- 0.4 mmol/l (group V). Basal glomerular filtration rate (GFR) and renal plasma flow (RPF) averaged 95 +/- 4 and 476 +/- 29 ml.1.73 m-2.min-1, respectively, and rose to 98 +/- 5 and 506 +/- 40 (group I) [P = not significant (NS)], 102 +/- 3 and 533 +/- 30 (group II) (P < 0.05 vs. basal), 110 +/- 4 and 567 +/- 29 (group III), 115 +/- 7 and 610 +/- 55 (group IV), and 117 +/- 7 and 614 +/- 66 ml.1.73 m-2.min-1 (group V) (P = NS vs. group IV). Basal plasma glucagon concentration averaged 68 +/- 10 pg/ml and increased to 74 +/- 10 (group I), 83 +/- 11 (group II) (P < 0.05 vs. basal), 100 +/- 14 (group III), 121 +/- 14 (group IV), and 229 +/- 35 pg/ml (group V) (P < 0.01 vs. basal). Increases in plasma growth hormone (GH) and insulin levels were observed only during groups IV and V.(ABSTRACT TRUNCATED AT 250 WORDS)

The Individual

Tonometry is a minimally invasive method for estimating gastrointestinal intramural pH (pHi). Tissue pH is calculated by using the Henderson-Hasselbalch equation and measurements of arterial [HCO-3] and CO2 tension (PCO3) of saline contained in a Silastic balloon within the lumen of the gut. The validity of the method rests on two key assumptions: 1) PCO2 in saline in the tonometer balloon is similar to tissue PCO2 and 2) tissue and arterial [HCO-3] are similar. To validate this method, ileal pHi measured directly with a microelectrode was compared with pHi estimated tonometrically in four groups of anesthetized pigs. Group I (n = 4) were controls. In group II (n = 4), intestinal tissue acidosis was induced by total occlusion of the superior mesenteric artery (SMA). In group III (n = 5), acidosis was induced by partial occlusion of the SMA. In group IV (n = 4), tissue acidosis was induced by endotoxemia. Agreement was excellent between direct and tonometric measurements in groups I and IV and less good in groups II and III. Weighted mean correlation coefficients (rw) for the two measurement methods were 0.743 and 0.9447 in groups II and IV, respectively. Correlation coefficients for the individual animals in group III were more variable than the other groups and ranged from 0.547 to 0.990. The tonometric method for measuring GI pHi is invalid under conditions of zero flow and leads to error under conditions of low flow. However, the method is reliable in the setting of tissue acidosis induced by endotoxemia.

The effect of concurrent exposure of toxic concentrations of lead and endosulfan were evaluated on oxidative stress parameters in male wistar rats. Group I served as untreated control whereas Group II received drinking water containing lead as lead acetate @1000 ppm (Pb1000). Group III was exposed to feed containing technical grade endosulfan @ 100 ppm (E100). Group IV was exposed to Pb (1000) +E (100). All the treatments were given daily for 28 days. Combination of lead and endosulfan modified the indices of oxidative stress in the parameters such as lipid peroxidation, reduced glutathione, superoxide dismutase and catalase in rats as compared to their individual compounds. The results suggest that the combination of these individual compounds may have the potential to modify oxidative stress produced by single compounds in male rats
