Research was conducted to determine the effect of diclofop or HOE-6001 on barley alpha-amylase level and diastatic power of malt from seven barley genotypes. Neither herbicide consistently decreased alpha-amylase level or diastatic power of barley malt. However, alpha-amylase level of the genotype Manley was decreased by all herbicide treatments in 1989. Results indicate that these herbicides should not affect the enzyme potential of barley.Key words: Diclofop, HOE-6001, amylolytic enzymes, alpha-amylase, diastatic power

Spearman’S Correlation

Objective: Several studies have tried to objectively assess pain measurements. The Wong-Baker Faces Pain Scale (WBFPS) is an instrument that is commonly used to assess pain intensity in children. This study aimed to analyze the correlation between the WBFPS and salivary alpha-amylase (SAA) level during a tooth extraction procedure with a local anesthetic injection in children aged 6–11 years.Methods: Twenty-five children aged 6–11 years who were to undergo the extraction of a primary tooth at the Dental and Oral Educational Hospital, Faculty of Dentistry Universitas Indonesia, were enrolled in this study. From all children, saliva was collected using a disposable saliva strip shortly after local anesthetic injection, and the SAA activity was then determined using a portable Nipro Cocoro Meter device. The WBFPS was measured at the same time. The correlation between the WBFPS and the SAA level was analyzed using Spearman’s correlation test. The statistically significant level was set at p≤0.05.Results: There was a significant correlation between the WBFPS and SAA level (p=0.002, r=0.581).Conclusion: Our data suggest that the SAA level might be a good index for objective pain intensity assessment.

The study was done to determine the effect of Tacca starch loading on production of amylolytic enzyme from Ragi Tapai. In this study, Ragi Tapai was used as a starter to produce amylolytic enzyme. The fermentation was done in a solid state fermentation with the presence of Tacca leontopetaloides starch as the carbon source. The analysis of total sugar was conducted using DNS method and amylolytic enzyme was determined using Lowry method. The mixture was fermented and incubated for 24, 48, 72 and 96h. The result revealed that the optimum production of amylase was found at 48 h of incubation with amylase activity of 1.91 U/ml/min and 1.42 mg/ml for total protein. The study shows that increment amount of the Tacca starch in cultivation medium, increase the production of the amylase and total protein content. The highest enzyme activity was obtained at 4% of Tacca starch loading with amylase activity and total protein content of 2.14 U/ml/min and 1.42 mg/ml respectively. The study indicated that growth promoters in Tacca starch capable to enhance the activity of microbial consortium in Ragi Tapai for production of the amylolytic enzyme.

Digestive Enzyme Activities

Abstract Carnivorous plants within the order Caryophyllales use jasmonates, a class of phytohormone, in the regulation of digestive enzyme activities. We used the carnivorous butterwort Pinguicula × Tina from the order Lamiales to investigate whether jasmonate signaling is a universal and ubiquitous signaling pathway that exists outside the order Caryophyllales. We measured the electrical signals, enzyme activities, and phytohormone tissue levels in response to prey capture. Mass spectrometry was used to identify proteins in the digestive secretion. We identified eight enzymes in the digestive secretion, many of which were previously found in other genera of carnivorous plants. Among them, alpha-amylase is unique in carnivorous plants. Enzymatic activities increased in response to prey capture; however, the tissue content of jasmonic acid and its isoleucine conjugate remained rather low in contrast to the jasmonate response to wounding. Enzyme activities did not increase in response to the exogenous application of jasmonic acid or coronatine. Whereas similar digestive enzymes were co-opted from plant defense mechanisms among carnivorous plants, the mode of their regulation differs. The butterwort has not co-opted jasmonate signaling for the induction of enzyme activities in response to prey capture. Moreover, the presence of alpha-amylase in digestive fluid of P. × Tina, which has not been found in other genera of carnivorous plants, might indicate that non-defense-related genes have also been co-opted for carnivory.
