Natural medicinal systems such as Ayurveda and folk medicine has remedies for wound management. However, the exact cellular and extracellular mechanisms involved in the healing process and its influence on keratinocytes is less discussed. Therefore, the present study was designed to evaluate the effect of certain natural wound healing medicines on the biology of the keratinocytes/HaCaT cells. Test materials such as honey (H), ghee (G), aqueous extracts of roots of Glycyrrhiza glabra (GG) and leaves of Nerium indicum (NI) were considered. The HaCaT cells were treated with the test materials singly and in combinations (H+G, all combined [Tot]) for a specific period (24, 48, and 72 hours). The cells were then subjected to cytotoxicity/proliferation and migration/scratch assays. All the test materials, except NI, were non-cytotoxic and showed increased cell proliferation at variable concentrations. Significant observations were made in the groups treated with honey (100 µg/ml at 48 hours, P<0.05; 1,000 µg/ml at 72 hours, P<0.05), GG (all concentrations at 48 hours, P<0.05; 750 µg/ml at 72 hours, P<0.05), H+G (250 µg/ml at 24 hours, P<0.001; 500 µg/ml at 48 and 72 hours, P<0.05), and Tot (50 µg/ml at 24, 48 and 72 hours, P<0.01). In the in-vitro wound healing assay, all the treated groups showed significant migration and narrowing of the scratch area by 24 and 48 hours (P<0.001) compared to control. The results obtained from the present study signifies the positive influence of these natural wound healing compounds on keratinocytes/HaCaT cells.

Here we present a unique case of variation in the branching pattern of the coeliac trunk. In the present case, the coeliac trunk was replaced by two separate arterial trunks. The first arterial trunk bifurcated into the left gastric and the left hepatic arteries. The second arterial trunk bifurcated into a splenic artery and a hepato-gastroduodenal trunk. The hepato-gastroduodenal trunk presented an unusual course and termination. The right hepatic artery arising from the hepato-gastroduodenal trunk also showed a variant course. Such rare variations are important for gastroenterological surgeons and interventional radiologists due to increase in number of transplantation surgeries and live donor liver transplantations.

The extensor digitorum brevis muscle (EDB) is a practical option for use as an island flap or free flap when reconstructing soft tissue defects in the ankle as well as in the entire lower limb. It is frequently used to correct crossover toe deformity and other painful toe disorders. We evaluated the morphometry of the EDB in 44 formalin-fixed limbs. Length and width of the muscles were measured. Surface area was calculated as the product of length and width of the muscle. The length of each tendon was also measured from its origin to the point of distal attachment. Presence of any additional tendons was noted. Mean length, width, and surface area of the muscle were 7.39+/-0.71 cm, 4.1+/-0.37 cm, and 30.5+/-4.78 cm2 on the right side and 7.2+/-0.84 cm, 3.9+/-0.37 cm, and 28.4+/-5.35 cm2 on the left side, respectively. Morphometry of the tendons revealed that the tendon of the great toe had the highest mean length (9.5 cm) and the tendon of the fourth toe had the lowest mean length (6.3 cm). Four of the limbs studied (9.09%) had only three tendons. Three of the limbs studied (6.81%) had five tendons, and in one exceptional case (2.27%), six tendons were detected. These observations have significant value and are applicable to plastic and orthopedic surgery.
