The objective of the current study was to determine the chemical constituents and fumigant toxicity of an essential oil that was isolated via hydrodistillation from dry leaves of Vitex pseudo-negundo (Hausskn.) Hand.-Mzz. The chemical composition of the essential oil was assessed via GC and GC-MS. 1, 8-Cineol (18.23%), α-Pinene (16.20%) and Sabinene (5.67%) were determined to be the major constituents of the oil. The fumigant toxicity of the essential oil was tested against 1–7 day-old adults of Tribolium castaneum (Herbst) and Sitophilus oryzae (L.) at 27±1 °C and 60±5% r.h. in darkness. The mortality of adults was tested at different concentrations ranging from 37.0 to 925.9 μL/L air and different exposure times (1–30 h). The results demonstrated that the mortality increased with increases in concentration and exposure time. At concentrations higher than 185.2 μL/L air, the mortality was recorded at more than 50% after 10 h, and reached 100% after 12–16 h. Data probit analysis demonstrated that S. oryzae (LC50=31.96 μL/L air) was more susceptible than T. castaneum (LC50= 47.27 μL/L air). These results showed that the essential oil from V. pseudo-negundo could be applicable to the management of populations of stored-product insects.

Presently, the world population of the elderly is growing. By improving health hygiene and welfare indicators, mortality and birth rates decrease and life expectancy increases, making the present century the century of elderly. Aging is one of the main risk factors for development of cancer, which itself is the second cause of death in old people. This study was conducted to assess the prevalence of cancer in the elderly covered by the Islamic Republic of Iran Broadcasting (IRIB) insurance program and to obtain suitable programs for cancer screening and early detection, increase patient survival, improve elderly care and to reclaim the cost of treatment in comparison to the national and international statistics. This is a cross-sectional study conducted on all elderly patients diagnosed with malignancy based on their pathology reports. In this study, of the total 75,500 patients covered by IRIB insurance, 17.2% belonged to the elderly group, males accounting for 53.3%. The most common cancers in old men were prostatic cancer (61.3%), colon cancer (10.3%) cancer of the hematologic system, bladder cancer (9.6%), lung cancer (9.1%), thyroid cancer (3.9%) and brain tumors (1.3%). In the elderly women, the most common cancers were breast cancer (80.1%), colon cancer (5.1%), thyroid cancers (4.4%), bladder and hematologic system malignancies (3.6), lung cancer (2.9%) and brain tumors (0.7%). In addition, the prevalence of cancer was almost the same as national and international statistics. With the exception of non-melanoma skin cancer no difference was shown in prevalence of cancer between IRIB elderly patients and the other groups of cancer patients in Iran.
