Evaluation of wound healing activity of Lantana camara L. - a preclinical study.

Lantana camara is used in herbal medicine for the treatment of skin itches, as an antiseptic for wounds, and externally for leprosy and scabies. The objective of our study was to investigate excision wound healing activity of the leaf extract of L. camara in rats. The animals were divided into two groups of 12 each in both the models. The test group animals were treated with the aqueous extract of L. camara (100 mg/kg/day) topically and the control group animals were left untreated. Wound healing efficacy was measured by determining the morphological and biochemical parameters. Wound healing time, wound contraction and synthesis of collagen were monitored periodically. Antimicrobial activities of the extract against the microorganisms were also assessed. Treatment of the wounds with extract enhanced significantly the rate of wound contraction (98%), synthesis of collagen and decreased mean wound healing time. These studies demonstrate that L. camara is effective in healing excision wounds in the experimental animal and could be evaluated as a therapeutic agent in tissue repair processes associated with skin injuries.

Investigation of wound healing activity of Lantana camara L. in Sprague dawley rats using a burn wound model.

Summary: Lantana camara is used in herbal medicine for the treatment of skin itches, as an antiseptic for wounds, and externally for leprosy and scabies. The objective of our study is to investigate burn wound healing activity of the leaf extract of L.camara in rats. The animals were divided into two groups of 6 each. The test group animals were treated with the ethanol extract of L. camara (100 mg kg-1 day-1) topically and the control group animals were left untreated. Healing was assessed by the rate of wound contraction, period of epithelialization. Antimicrobial activities of the extract against the specific microorganisms were assessed. The extract showed antimicrobial activity against Staphylococcus aureus, Klebsiella Pneumoniae and E.coli. Extract treated wounds were healed in about 21 days which is not distinct from the controls. Our data suggest that L.camara has antimicrobial activity but not wound healing promoting activity on burn wound. Industrial relevance: Extensive work has been done on the L. camara and demonstrated the antimicrobial and fungicidal activity of its chemical constituents. Lantana oil is used for the treatment of skin itches and as an antiseptic for wounds. It has been used in folk medicine for the treatment of cancers, chicken pox, measles, ulcers, swellings, eczema. Our earlier work showed the healing activity on excision wound model. However, there is no data to support the wound healing activity of L. camara on burn wound. Hence, we have conducted the present study to explore the wound healing activity and the antimicrobial activities of L. camara against the specific microorganisms which generally infect burn wound.

Dapsone induced pulmonary eosinophilia without cutaneous allergic manifestations--an unusual encounter--a case report.

Dapsone is a drug of choice in the treatment of leprosy. In addition it is very useful in the treatment of many other dermatological conditions. The "dapsone-induced hypersensitivity" is not unknown. However, to the best of our knowledge, pulmonary eosinophilia induced by dapsone without any cutaneous allergic manifestation has not been reported in leprosy patients. Pulmonary eosinophilia (Loeffler's syndrome) induced by dapsone without cutaneous manifestation has been reported in a non leprosy patient by Janier et al. We report a case of pulmonary eosinophilia associated with dapsone therapy in a patient with lepromatous leprosy without allergic cutaneous manifestations and our experience in the management of this patient.
