Abstract
The aim of this study was to compare the efficacy of ceftriaxone plus vancomycin (Vancoplus) versus ceftriaxone alone against cephalosporin resistant methicillin-resistant Staphylococcus aureus (MRSA) strain by using meningitis mice model. The MRSA strain ATCC 43300 was used to induce meningitis in mice. The mice were fed standard pelleted diet and water ad libitum. The test room was air conditioned with temperature 23 +/- 2 degrees C, humidity 65+/- 5% and with artificial fluorescent light 10-14 hrs. of light and dark, respectively. Twenty four mice were divided into four group containing six rats in each group. The ceftriaxone group received 28.57 mg/Kg body weight/day and the vancoplus group received 42.8 mg/Kg body weight/day and control as well as infected group received normal saline. The bacterial susceptibility test in CSF was performed for cephalosporin resistance MRSA strain by determining the lytic zone for the vancoplus and ceftriaxone antibiotic. The lytic zone was more in vancoplus as compared to ceftriaxone. It was also found that activities of antioxidant enzymes such as catalase were significantly increased (p<0.001) along with decreased (p<0.001) in lipid peroxidation (malonaldialdehyde) level in CSF of vancoplus treated group as compared to infected as well as ceftriaxone resistance group and come back to normal level. It was concluded that vancoplus beneficial for the patients who suffered from cephalosporin resistant MRSA bacterial strain.

Abstract
Pneumonia is a severe infection that causes high morbidity and mortality rate worldwide. It is caused by Klebsiella pneumoniae, which generally causes upper respiratory tract infection. In case of such type of infection, levels of oxidant and antioxidant become imbalanced, which may contribute to lung injury. The present study was planned to evaluate the status of oxidant and antioxidant enzyme activities in plasma and lung tissue of pneumonia-infected rats model. Animals were randomly distributed into 3 groups of 8 rats each: groups I (control, normal saline treated), II (infected group), and III (infected + treated group). The findings showed that there was significant increase (P < .001) in body temperature along with decreased body weight in the infected group as compared to the control group. Similarly, all the activities of antioxidant enzymes (superoxide dismutase [SOD], catalase) were significantly decreased along with increased malonaldialdehyde (MDA) levels in plasma and lung tissue of the infected group as compared to the control group. These enzyme activities along with MDA levels were improved and came back near to normal level after administration of cefepime plus amikacin (potentox) for 7 days in group III. These studies concluded that fixed-dose combination of potentox improved oxidant and antioxidant levels in pneumonia infection.

Abstract
BACKGROUND In recent decades, there has been a tremendous surge of interest in issues related to child health. The present study was carried out to reveal the DMFT/deft status of children in the age group of 1-12 years, residing in orphanages from Pune, India. AIMS AND OBJECTIVES To explore the DMFT/deft status in various orphanages from Pune (India). To find out differences, if any, between the DMFT/deft status in orphanages from Pune, India, and the general population of children below 12 years of age in Maharashtra state, India as well as all over India. RESULTS DMFT/deft of the orphanages was found to be 2.58 in the age group 1-5 years and 2.5 in the age group 6-12 years with caries prevalence in 70.27% of the children. An incidental finding of Molluscum contagiosum was observed in a significant percentage of children. The total percentage of children afflicted by Molluscum contagiosum was found to be 24.32%. CONCLUSION The higher incidence of Molluscum contagiosum in children residing in orphanages as compared to the normal population of the same age group was reflected in the higher incidence of DMFT/deft in orphanages as compared to the normal population.

Abstract
BACKGROUND The purpose of this study was to evaluate the biological aggressiveness of odontogenic keratocyst/keratocystic odontogenic tumour (KCOT), radicular cyst (RC) and dentigerous cyst (DC) by observing the actual proliferative activity of epithelium, and p53 protein expression. METHODS The actual proliferative activity was measured by Ki-67 Labelling Index and argyrophilic nucleolar organizing regions (AgNOR) count per nucleus. The p53 protein expression was also evaluated. RESULTS Ki-67 positive cells were observed higher in suprabasal cell layers of KCOT with uniform distribution, a few of them were predominantly observed in basal cell layer in RC and DC. The AgNOR count was significantly higher in suprabasal cell layers of KCOT. The actual proliferative activity was noted to be higher in suprabasal cell layers of KCOT. The p53 immunolabelling was dense and scattered in basal and suprabasal cell layers in KCOT. The weakly stained p53 positive cells were observed diffusely distributed in KCOT, whereas they were mainly seen in basal cell layer of RC and DC. CONCLUSION The quantitative and qualitative differences of the proliferative activity and the p53 protein expression in sporadic KCOT may be associated with intrinsic growth potential that could play a role in its development and explain locally aggressive biological behaviour. AgNOR count and p53 protein detection in odontogenic lesions can be of great consequence to predict the biological behaviour and prognosis.

Abstract
Chikungunya fever is an important arboviral infection prevalent throughout Africa and Southeast Asia. Recently, in 2006, it has reemerged in many parts of India, affecting more than a million persons. A detail serological, virological, and molecular investigation of this unprecedented outbreak was carried out by collecting and studying 540 samples from all the affected regions of India during this epidemic. An in-depth investigation revealed the presence of anti-Chikungunya antibodies in 68% of the samples and genomic RNA in 49% of them. In addition 32 Chikungunya viruses were isolated from 45 representative polymerase chain reaction-positive samples. The nucleotide sequences of partial E1 gene of 25 representative Chikungunya viruses were deciphered. The sequence analysis indicated that all the isolates of this epidemic belonged to the new Indian Ocean island clade of East Central South (ECS) African genotype. This study conclusively proved the genotype shift from Asian to ECS African as the major factor in the reemergence of Chikungunya in an unprecedented outbreak in India after a gap of 32 years.

Abstract
OBJECTIVES To evaluate, retrospectively, the impact of penile correction by modeling of the penis over an inflatable penile prosthesis and the subsequent improvement in erectile function. Advanced Peyronie's disease with severe penile curvature and poor quality erections presents a challenge to the urologist. METHODS In our series, 46 patients with advanced Peyronie's disease and associated erectile dysfunction underwent insertion of an inflatable penile prosthesis between 1998 and 2003. Of the 46 patients, 28 (61%) underwent a standard modeling procedure; the other 18 patients (39%) did not need additional modeling, because their curvature was corrected by inflation of the prosthesis alone. Patients were evaluated postoperatively in the clinic, as well as by a postal questionnaire. RESULTS Of the 46 patients, 44 were satisfied with the penile correction and 2 (4.4%) underwent removal of their prosthesis because of infection. These 2 patients underwent revision surgery; subsequently both prostheses had to be removed, one for severe pain and the other for urethral erosion. None of the patients underwent reoperation for additional straightening. Of the 44 patients with intact prostheses, erectile function significantly improved in 41 (93%). CONCLUSIONS The results of our study have indicated that patients with severe Peyronie's disease and erectile dysfunction should be offered the choice of penile modeling over an inflatable penile implant to correct the curvature, as well as improve erectile function.

Abstract
BACKGROUND/AIMS Leptin, the ob/ob gene product, is a recently discovered peptide hormone, secreted by adipocytes, which can act as a satiety factor to regulate food intake. Its levels thus will be related to the presence of food in the lumen of the gut, and food intake is one of the most potent stimuli for intestinal epithelial cell proliferation. Leptin has a variety of other actions and the aim of this study was to see if one of these was to stimulate mucosal growth. METHODS Three groups of mice were fed ad libitum, starved for 48 h or starved for 48 h and given twice-daily intraperitoneal injections of recombinant leptin (1 microg/g). RESULTS Starvation led to a 20% decrease in body weight and a similar decrease in the weights of the intestines. Starvation also markedly inhibited intestinal epithelial cell proliferation. Leptin had little effect on the small intestine and did not stimulate proliferation. However, in the hind gut it was associated with small but significant decreases in caecal weight, distal colon mitotic counts (p = 0.036) and in colonic crypt area (approximately 20%, p<0.001). CONCLUSION Leptin did not stimulate intestinal cell proliferation, however it did have a paradoxical inhibitory action on the caecum and colon.

Abstract
Study was carried out in 100 patients of non-specific vaginitis (NSV) to find out the incidence of vaginitis due to G. vaginalis. Out of a total of 100 subjects 20 were positive for G. vaginalis as compared to only 6 in equal number of normal matched controls. One positive specimen showed concomitant presence of C. albicans and E. coli was found in another positive specimen. Presence of amines and clue cells in the discharge did not correlate with the isolation rate of G. vaginalis, thus emphasizing the necessity of culture to diagnose NSV due to G. vaginalis.

Abstract
The study was conducted on 92 root canals selected from teeth advised for extraction to evaluate the efficacy of an electronic device (NEOSONO D-SE), Ingles method and Digital Tactile method for the measurement of working length of tooth. In 30% of anterior teeth and 30% of posterior teeth the electronic device was able to locate exact position of apical constriction of tooth, as measured after the extraction of the tooth. In 37% of anterior teeth and 13% of posterior teeth, the apical constriction was located exactly when digital tactile method was used. When Ingle's method for determining the working length was used it was successful in 30% of anterior teeth and 42% of posterior teeth. The study was also conducted to know the distance between apex of the tooth to apical foramen and distance between apical foramen and apical constriction. The findings of the study showed that the average distance between apex and apical foramen was 0.215mm and 0.289 mm in anterior and posterior teeth respectively. Whereas the distance between apical foramen and apical constriction was 0.610 mm and 0.504 mm in anterior and posterior teeth respectively.

Abstract
Eight 5-(3,4-methylenedioxyphenyl)-3-arylaminomethyl-1,3,4-oxadiazole-2-thiones were synthesized, characterized by their sharp melting points, elemental analyses, and IR spectra, and evaluated for anticonvulsant activity. All substituted oxadiazole-2-thiones possessed anticonvulsant activity, which was reflected by their ability to provide 10--70% protection against pentylenetetrazol-induced convulsions in mice at 100 mg/kg ip. These compounds inhibited in vitro nicotinamide adenine dinucleotide (NAD)-dependent oxidation of pyruvate, alpha-ketoglutarate, and NADH by rat brain homogenates as well as NAD-independent oxidation of succinate by rat brain homogenates. Antiproteolytic activity of these substituted oxadiazole-2-thiones was reflected by their ability to inhibit trypsin hydrolysis of bovine serum albumin. These results indicated that the inhibition of cellular respiration and antiproteolytic activity of these substituted oxadiazole-2-thiones is not the biochemical basis for their anticonvulsant activity.
