Some physiochemical properties of water quality of Otamiri-oche River which runs through Imeh, Edegelem and Chokocho Communities in Etche ethnic nationality of Rivers State, Nigeria were investigated. Samples were collected in triplicate from the three different locations along the river in both rainy and dry seasons. Each sampling points is located 500m away from the successive one, and the samples were taken from the open river at the zone extending beyond the shoreline. Samples were stored in ice packs and immediately taken to the laboratory to investigate some selected physico-chemical characteristics. Also, bacteriological study was carried out on the samples. The laboratory results of the selected physico-chemical parameters when compared with the world health organization (WHO) standard showed that all the selected physico-chemical parameters were within the world health organization (WHO) permissible in both rainy and dry season except pH. For rainy season, the pH values were 5.00±0.00, 5.40 ±0.40, and 5.40± 0.30 for Imeh, Edegelem and Chokocho respectively. For the dry season, the pH values were 5.83± 0.01, 5.56±0.01, 5.90±0.01 for Imeh, Edegelem and Chokocho respectively. Also magnesium hardness exceeded the World Health Organization (WHO) permissible limit in rainy season only. The results of bacteriological study showed that all the sampling locations contained high numbers of coliform bacteria in both rainy and dry seasons. The number of coliform bacteria during rainy season was 25.00±0.00, 25.00±0.00, and 35.00±0.00 for Imeh, Edegelem and Chokocho respectively. Those of dry season were 93.00±3.55, 56.66±4.49, and 35.60±4.17 for Imeh, Edegelem and Chokocho respectively. The difference between the rainy and dry season was tested statistically using the t-test. The results of the statistical analyses showed a significant difference (p<0.05) between the rainy and dry seasons.

Se elaboraron Procedimientos Estándar de Operación basados en la Guía de Evaluación de Buenas Prácticas Manufactura para Laboratorios Farmacéuticos de la Dirección Nacional de Medicamentos, la cual consta de once capítulos y de los cuales se elaboraron los Procedimientos Estándar de Operación de los capítulos uno (Organización y Personal), tres (Edificios e Instalaciones), seis (Empaque) y siete (Operaciones de Calidad). Todos estos procedimientos podrán ser utilizados como herramientas en el Laboratorio de Tecnología Farmacéutica para dar a conocer la importancia del cumplimiento de las Buenas Prácticas de Manufactura a los estudiantes de la carrera de Licenciatura en Química y Farmacia, también se presenta un cuadro comparativo entre la actual Guía de Evaluación de Buenas Prácticas de Manufactura para Laboratorios Farmacéuticos de la Dirección Nacional de Medicamentos (DNM) con el informe 32 de la Organización Panamericana para la Salud (OPS), en el cual se evidencia que todos los puntos de evaluación de la guía de la DNM, se encuentran presentes en la guía de la OPS, además se pueden tomar las debilidades y corregirlas para hacerla más completa la cual haría más competitivos a nivel local e internacional a los Laboratorios Farmacéuticos nacionales.
