CSC and 1PM from four different commercial filtered cigarettes were applied to the CAMs on day 4 of incubation. Macroscopic vascular transformations were evidently observed among all treated CAMs. Applications of CSC disk caused sturdy obliteration of main blood vessels, while whole architecture of the secondary and tertiary vasculalure was completely destroyed. Likewise, application of '1PM from all brands of cigarette caused disproportionate thinning of all primary and secondary blood vessels. Reduction in the total area and diameter of primary, secondary and tertiary blood vessels were observed after treatment with CSC and TPM. 1-listological evaluations revealed loss of ectodermal and mesodermal integrity in botl'i types of treatments. Scanty capillary plexuses formation, deterioration of extracellular matrix and delayed migration of blood vessels were prominent findings among all treated groups. Results obtained from CSC treated groups were more localized, while generalized results were prominently recorded in 1PM treated groups. Special considerations of CSC and 1PM should he given while smoking during pregnancy and after surgery because it may severely affect the process of angiogenesis, which is vital in maintenance of pregnancy and wound healing.

The cigarette smoke condensate (CSC) and total particulate matter ('1PM) of cigarette smoke is sternly toxic to health and may produce several pathologies. In our study, we have focused on the toxicological effects of CSC and '1PM on different events of angiogenesis using chicken chorioallantoic membrane assay (CAM). CSC and 1PM from four different commercial filtered cigarettes were applied to the CAMs on day 4 of incubation. Macroscopic vascular transformations were evidently observed among all treated CAMs. Applications of CSC disk caused sturdy obliteration of main blood vessels, while whole architecture of the secondary and tertiary vasculalure was completely destroyed. Likewise, application of '1PM from all brands of cigarette caused disproportionate thinning of all primary and secondary blood vessels. Reduction in the total area and diameter of primary, secondary and tertiary blood vessels were observed after treatment with CSC and TPM. 1-listological evaluations revealed loss of ectodermal and mesodermal integrity in botl'i types of treatments. Scanty capillary plexuses formation, deterioration of extracellular matrix and delayed migration of blood vessels were prominent findings among all treated groups. Results obtained from CSC treated groups were more localized, while generalized results were prominently recorded in 1PM treated groups. Special considerations of CSC and 1PM should he given while smoking during pregnancy and after surgery because it may severely affect the process of angiogenesis, which is vital in maintenance of pregnancy and wound healing.
