Effect of cadmium,copper, and zinc on the growth of blackgram

Blackgram (Vigna mungo, L.) growth was measured in a glasshouse earthen‐pot experiment. Cadmium (Cd), copper (Cu), and zinc (Zn) were applied in different concentrations to the soil. The plant and soil samples were analysed 45 days after sowing using ICP‐AES. The dry matter yield of tissue showed highly significant reduction (at the 1% level) for Cd and Cu, and nonsignificant variation for Zn. This shows that phytotoxicity for Cd and Cu was greater than that for Zn. Further, the observed higher correlation coefficients suggest that the concentration of the elements in tissue is linearly related to that applied to the soil.     

A novel technique for ventral orbital stabilization: the masseter muscle flap

Loss of the caudal maxilla and ventral orbit after tumor resections can have negative functional and esthetic influences on the eye involved. This article reports on a case of a caudal maxillary acanthomatous ameloblastoma involving the ventral orbit that was resected and stabilized with a masseter muscle flap. The masseter muscle flap was generated from the superficial belly of the masseter muscle in order to close a defect in the orbital rim, created by a caudal maxillectomy. None of the published complications such as enophthalmos, excessive lacrimation, globe deviation, or strabismus were noted, 8 months following the procedure. The only clinical sign present at the time of re‐evaluation was mild lacrimation. The authors propose the use of a masseter muscle flap as a viable technique in stabilizing the ventral orbit after caudal maxillectomy and ventral orbitectomy, preventing the complications associated with this surgery.
