Abstract

Ethanolic leaf extract of Saurauia vulcani Korthor pirdot in Indonesia was evaluated to improve the number of erythrocytes in laboratory rats after being immunized with sheep red blood cells (SRBC). This study was conducted in an experimental manner using a non-factorial Completely Randomized Design (CRD) with four treatments and six replications. The tested animals were 24 rats (Rattus norvegicus) maintained in the laboratory. The experimental designs were designated as follows: G0as a control group treatedwith regular animal feed,G1 was treatedwith 0.1 mLSRBC, G2was treated with 500 mg ethanolic leaf extract of Saurauia (EES)/kg body weight (BW), G3 was treated with 500 EES/kg BW and 0.1 mL SRBC. The immunological effect was monitored by analyzing the level of interleukin-2 (IL-2) using ELISA, lymphocytes using ABX Microx 60, and liver histopathology. The results showed that lymphocyte levels was increased in G2 and G3 but not significant to G0. The IL-2 level in G1 was recorded the highest among groups due to the treatment using SRBC. The percentage of necrotic cells in G1was 5.8%, followed by G3 with 2.3%. The morphologies of liver histology were normal, parenchymatous and hydropic degenerations, and necrosis. The phytochemical constituents in ethanolic leaf extract of S. vulcanipossessed an immunological effect through the increased lymphocytes, reduction of IL-2, and protection through normal liver histopathology in rats.

Abstract

Levels of air pollution caused by motor vehicles in the big cities in Indonesia is quite high, about 60%was alarming and impact on public health. The main problem is why should conduct an effectivetesting of emissions vehicles in Indonesia? Tire aim of study is to provide recommendations haw toreduce emissions levels, the object of studtj is the implementation of emissions testing, characteristicsand facilities. The method used is to compare with the threshold determined btJ the data from variousofficial. sources.Tire success of reducing emissions levels is in the supervision of testing and legal action in its testingsystem.Need to reform its institutions emissions testing, technician certification, the appointment of calibrationinstitution, improving information systems, certification, and socialization to the communihJcontinuously.Keyword: Emissions and public health.
