Abstract:- The left lung classically has one fissures, an oblique, dividing it into two lobes namely these are superior and inferior. The anomaly of the lobar pattern has been described by many research workers on CT scans and X- rays butthere are fewer studies on gross anatomical specimens. In the present case , which was incidentally detected, we report two fissures dividing the left lung into three lobes. Such abnormal fissures and lobes are clinically important for identifying broncho-pulmonary segments. Anatomical knowledge of anomalies of fissures and lobes of lungs may be important for surgeons performing lobectomies, radiologists interpreting X ray and CT scans and also academic interest to all medical personnel.
Key words:- Anomaly; Anatomical variation; Abnormal; Fissure; Lobe; Lung.

Abstract: Background & Objectives: Fixed Prosthodontics is one of the most commonly practiced treatment modality throughout World. With the advent of latest advancements in the field of Fixed Prosthodontics, failure rate have also increased. A poor marginal integrity accounts for most of these failures. This study was undertaken to determine the comparative accuracy of six different probes in evaluating marginal gap and to check the influence of vision on evaluation of marginal discrepancies in restorations. Method: Thirty evaluators post graduate students from Bapuji Dental College and Hospital, Davangere were chosen at random. Two stainless steel plates were made. Grooves of known dimensions ranging from 35um - 165um were machined onto the surface. In order to avoid conditioning bias, on one plate the grooves were arranged in a random order. The evaluators were asked to indicate the presence of the grooves present on the plates through probing in direct vision and indirect vision (by using a barrier). Statistical Analysis: The statistical analysis was carried out using the Statistical Package for Social Scientists (SPSS), Repeated Measures of ANOVA (f), Intraclass Correlation Co-efficient (ICC) and Karl Pearson’s Correlation Co-efficient (r). Results and Conclusion: The results showed that probe with the least tip diameter is the most accurate in identification of marginal discrepancy and that the bluntest probe is the least accurate. The results also indicated that there was no significant difference in evaluating marginal gap under direct vision or indirect vision, although, evaluation under direct vision was better. Key words: Marginal integrity; probes; vision.

Abstract: -
Aim: This study was aimed to evaluate the influences of interaction of Verapamil Hydrochloride with Zinc Sulphate on protein binding of drug in physiological pH and temperature. Materials and methods: The interaction between Verapamil Hydrochloride and Zinc Sulphate (anhydrous) has been studied in an aqueous system at a fixed temperature (37±0.5)0C and under pH 7.4 and 2.4 by a variety of physical method, to detect and confirm the nature of complexation of this drug with Zinc sulfate (anhydrous). The methods include- inspection of spectral behavior, Job’s method of continuous variation and Ardon’s straight line plots by spectrophotometer. The protein binding experiments of the free drugs as well as the combined systems were studied by equilibrium dialysis method. Results: From spectrophotometric study, it has been found that Verapamil Hydrochloride form 1:1 complex with Zinc Sulphate (anhydrous). Spectral studies helps to detect the initial complexation between drug and metal. Job’s plot at 7.4 and 2.4 provides same type of information. The Ardon’s spectrophotometric method confirmed the 1:1 complexation and the value of stability constants was calculated using Ardon’s plot. The Scatchard plots were prepared to reveal the number of binding sites and the affinity for protein binding. It has been found that interaction of the drug with Zinc Sulphate (anhydrous) results into increasing the affinity and increasing the protein binding of Verapamil Hydrochloride. Conclusion: The results show that Zinc sulphate (anhydrous) increases the percentage of protein binding of Verapamil hydrochloride at saturation zone. Key words:- Ardon’s method, Equilibrium dialysis, Protein binding, Scatchard plot, Verapamil Hydrochloride, Zinc Sulphate (anhydrous).

Abstract:- Introduction: Twins are of two types, monozygotic and dizygotic and the status of development of a child is usually assessed in relation to events that take place during progress of growth. Thus chronological age, dental development, height and weight measurements, sexual maturation characteristics and skeletal age are some biological indicators that have been used to identify time of growth. The objective of the study was to assess the correlation between the chronological age, dental age and skeletal age among twins of different types. Materials & methods: Panoramic and hand wrist radiographs of 30 twins between 8-16 years of age were evaluated and compared for correlation of dental, skeletal and chronological ages. Results: The result indicated that correlation exists between all three above characteristics among twin pairs of the same zygosity and sex, but no correlation exits between different zygotic twins and twins of different sex. Conclusion: There is Correlation between chronological age; dental age and skeletal age among monozygotic and dizygotic twins of the same sex whereas, no correlation exists between mixed sex pair twins. Keywords:- Monozygotic, dizygotic, panoramic, hand wrist radiographs.

Abstract: -Objective: A study was conducted to examine biopsy reports of lesions, diagnosed as oral lichen planus, with the hope that a set of parameters could be defined which would be more pathognomonic in diagnosing oral lichen planus, despite the variability of its presentation. Methods & Materials: Fifty histologically diagnosed cases of oral lichen planus were reviewed and were further categorized as oral lichen planus, nonspecific lichenoid stomatitis and lichenoid dysplasia, using well established histological criteria. Results: This study reveals an “Over diagnosis” to the extent of 14% through the inclusion of nonspecific lichenoid stomatitis as well as other conditions, including dysplasia, under the diagnosis of oral lichen planus. So non-uniformity among various pathologists in following the histomorphologic parameters in order to render a diagnosis of oral lichen planus has resulted in significant “Over diagnosis” of oral lichen planus. Conclusions: Aside from the obvious diagnostic errors, such oversight can lead to mistaken impressions concerning the natural behavior of relatively benign process. Hence, an attempt is made for reappraisal of histopathological designation of the lesions that have a lichenoid character.
