"The hypersensitive reaction (HR) jn plants is a plant defense system against pathogen attack. HR is characterized by the rapid death of infected cells accompanying the formation of necrotic lessions in which pathogens are thought to be enclosed. Following the early signaling events activated by pathogen attack, the elicitor signals are often amplified through the generation of secondary signal molecules such as salicylic acid (SA) and Jasmonate acid (JA). Some studies have shown thai SA- and JA-signaling pathways are interconnected in complicated ways and it is still not clear how defense response is modulated by SA and JA. To understand better the involvement of JA. the action of MeJA on harpin-induced HR was investigated by using tobacco plant (wildtype and transgenic carrying a chimeric gene of PSPAL2 promoter and GUS gene. Leaves of of tobacco were infiltrated with harpin and MeJA. The results from HR assay and GUS histochemical staining showed that induction of HR by harpin (250 ug/ml) seems to be modulated by 100 uM MeJA. These results suggest that exogenenously application of MeJA will affect the endogenous concentration in plant that will become a switching point for MeJA to lead the potentiation or suppression of defense response."

Malaria is an infectious disease which is still causing a public health problem in many parts of Indonesia. There are many endemic areas where the prevalence of malaria is high . The diagnosis of malaria is commonly done by clinical examination and parasite finding at microscopic examination of blood sample. Microscopic examination is still used as a gold standard for malaria diagnosis, however this method is less sensitivity and accuracy especially in low parasitemia.

Therefore, it is a need to develop an alternative method which is more sensitive and accurate fur Malaria diagnosis. PCR method for urine sample is being developed as an alternative diagnosis for Malaria. A total of 58 individuals living in malaria endemic areas participated in blood and urine collections. The presence of malaria parasites in blood samples were detected by microscopic examination whereas the DNA of mrdarial parasites, P. falciparum and P. vivax, in urine samples were detected by PCR method using ssu rRNA primers. Positive results of both malarial parasites were found in 42 samples with 98% sensitivity and 94 % specificity.

Diagnostic test of microscopic examination of blood samples and PCR of urine samples showed that 18 samples were P. falciparum positive with 94% sensitivity and 94% specificity whereas 25 samples were positive for P. vivax with 96% sensitivity and 94% specificity. This study revealed that PCR method can be used as an alternative diagnostic tool for malaria because it has high sensitivity and specificity (more than 90 %)."
