Abstract
Background: Angiogenesis is one of the most important biological processes which is characterized by the formation of new blood vessels in many developmental and pathological stages. Therefore, angiogenesis blockage using anti-angiogenic drugs can be effective in treatment of such diseases as hemorrhages and cancers. Citrullus colocynthis (bitter melon) is a medicinal plant with cytotoxicity effects that its anti-angiogenic effects were investigated in this study. Materials and Methods: In an experimental study, at first, Citrullus colocynthis alcoholic extract was prepared. Then, 30 Highline fertilized eggs were randomly divided into control, sham-exposed, and treatment groups. On the seventh day of incubation, the sham-exposed group was treated with normal salin and the treatment group was treated with the plant extract. On the 10th day of incubation, CAMs were examined and photographed by research photostereomicroscope. The number and length of vessels around the treated region were measured and analyzed through SPSS and t-test (p<0.05). Results: According to data analysis, the number (31.40±5.87) and length (46.60±7.33 cm) of vessels in the control group did not reveal a significant difference in comparison to the number (27±5.16) and length (42.40±5.05 cm) of vessels in the sham-exposed group. However, a significant decrease was observed in the number (6.70±2.05) and length (14.79±3.34 cm) of vessels in the treatment group in comparison to the control group(p<0.05). Conclusion: The alcoholic extract of Citrullus colocynthis seems to have had a repressive effect on angiogenesis in chick chorioallantoic membrane. Therefore, it decreases the number and length of vessels around the treated area.

Abstract
Background: Addiction is undoubtedly one of the biggest problems of human societies that every year governments spend enormous amounts of money on fighting it. Most addicts, besides their addiction, cause many psychological problems in their families therefore, the aim of this study was to compare the presence of these disorders between the families of addicts and non-addicts. Materials and Methods: This case-control study was done on a sample of 650 persons of opium addicts' and non-addicts' families using random sampling method. Data were collected through SCL-90-R questionnaire and were analyzed by Chi-square and t-test using SPSS software version 18. Results: There was a significant difference in psychiatric disorders in addicts' and non-addicts' families (p=0.005). Among the 9 psychiatric disorders under assessment, only anxiety, aggression, paranoia, and depression disorders in three types, including pathologic, borderline, and combined (pathologic-borderline), were significantly higher in addicts' families compared with non-addicts' families (p=0.005). Conclusion: Drug dependence disorder in one member of a family has a very important effect on the mental hygiene of the other family members and requires prevention and treatment in both.
