Effects of Monosodium Glutamate Oral Administration on LH and Testosterone Levels in Serum of Adult Male Rats (Rattus norvegicus)

However, in a statistical test, the group that took MSG (M1) for 15 days showed no significant difference with the control group. In addition, the decrease in serum testosterone was probably caused by the damage and decrease in the number of Leydig cells in the testes. In addition, the number of Leydig cells was significantly reduced compared to those in the control group.

This decrease in the number of Leydig cells was caused by an increase in ROS production in the testis [7]. This can lead to rupture of cell membranes and necrosis, causing a decrease in the number of Leydig cells [12]. A decrease in the number of Leydig cells affects testosterone production and testicular testosterone levels [14].

The Effect of Monosodium L-Glutamate (MSG) Treatment for Short and Long Terms to The Semen Quality of Adult Male Rats

Percentage of sperm viability and abnormality was examined by a light microscope at 400x magnification in 3 microscope fields (or up to 200 cells). Although there were no significant differences in the sperm motility between M1 and M2, the use of MSG short- and long-term caused a decrease in the percentage of sperm motility by 15.5%. Reduction of sperm motility can be affected by disruption of spermatogenesis in testes and sperm maturation in epididymis [17,18].

Thus, ATP depletion and disruption of membrane fluidity can lead to loss of sperm motility [21]. ROS can reduce sperm motility and sperm capacitation through membrane fluidity pathways, resulting in changes in sperm motility parameters (22). The highest sperm viability was found in the M0 group and the lowest in the M2 group with a decrease of 39.61% (Table 1).

The percentage of sperm abnormality (both primary and secondary abnormal) was highly significantly increased (p≤0.01) in the MSG treatment group (M1 and M2) compared to the control group (Figure 1).

The Study of Growth and Its Polyembryonic Properties of Porang Seeds (Amorphophallus muelleri Blume) from Various Fruit Colors in Different

Planting Media

This study aims to determine the potential of seeds from different fruit colors (red, yellow, green) and the effect of the composition of the planting medium used on the growth of A. The difference in fruit color is used as a sign of different ages of seeds. Seeds that were grouped based on fruit skin color were planted in a planting medium according to treatment (M1-M4).

The results of the ANOVA test showed that the time of shoot emergence was significantly affected by the interaction between seeds from different fruit colors and plant media. In this study, the level of ripeness is indicated by the color of the fruit (red, yellow and green). The results of the ANOVA test showed that the uniformity of germination was significantly affected by the interaction between seeds from different fruit colors and plant media.

However, the seeds of the yellow fruit, in addition to one shoot (monembryony), also produce 2, 3 and 4 shoots (polyembryony) in all types of planting media.

Alcohol Intake Investigation of Adult Rats Based on Sperm Parameters

In the previous result [12], the administration of 30% ethanol for 14 days could reduce the number, motility and morphology of spermatozoa, and the 21-day ethanol intake was considered more significant results due to the longer ethanol administration. Ethanol does not significantly affect sperm concentration because the metabolism of ethanol in the rat's body does not affect it. The ethanol-related decrease in sperm motility in the treated groups is one of a series of indicators that chronic ethanol consumption may compromise sperm structural integrity through the mitochondrial pathway.

Therefore, a reduced or impaired mitochondrial function will prevent sperm motility as observed in the alcohol-treated groups of this study. However, the decrease in persistence percentage in the ethanol treatment groups did not show a significant difference with the control rats. Under normal physiological conditions, endogenous antioxidants help maintain a low level of oxidative stress in sperm [25].
