This study was conducted to investigate effect of activated charcoal on growth and yield of Scutelltaria baicalensis G. in different degree of activated charcoal consistency. The results obtained are summarized as follows. Stem length was shown the longest in activated charcoal 30%, and short in control. Also stem diameter was shown the thickest in activated charcoal 30%, and thin in control. Length of main root and thickness of main root were good in activated charcoal 30%. Quality and yield of Scutellaria baicalensis G. were the highest by activated charcoal 30%. Therefore, optimum consistency of activated charcoal was activated charcoal 30%.

This study was conducted to investigate the effect of activated charcoal on growth and yield of taro in different degree of activated charcoal concentration. The results obtained are summarized as follows. Stem length was shown the longest in activated charcoal of 10-20％, but shorter in control. Also stem diameter was shown the thickest in activated charcoal of 10-20%, but thinner in control. Length of main root and thickness of main root were good in activated charcoal of 10-20%. Quality and yield of Bupleurum fatcatum was the highest in activated charcoal of 10-20%. Therefore, optimum consistency of activated charcoal was 10-20%.

This study was conducted to investigate the effect of activated charcoal on growth and yield of taro in different degree of activated charcoal concentration. The results obtained are summarized as follows. Stem length was shown the longest in activated charcoal of 10％∼20% , but shorter in control. Also stem diameter was shown the thickest in activated charcoal of 10％∼20%, but thinner in control. Length and thickness of main root and thickness of main root were good in activated charcoal of 10∼20% Quality and yield of taro was the highest in activated charcoal of 10∼20% . Therefore, optimum consistency of activated charcoal was 10∼20％.

The breakthrough behaviour of activated charcoal cloth samples against an oxygen analogue (OA) of sulphur mustard has been studied using the modified Wheeler equation. Activated charcoal cloth samples having different surface area values in the range of 481 to $1290m^2/g$ were used for this purpose. Breakthrough behaviour was found to depend on the properties of the activated charcoal cloth, properties of the OA and the adsorption conditions. Activated charcoal cloth with a high surface area of $1290m^2/g$, relatively large surface density of $160g/m^2$ and coarser fiber structure exhibited better kinetic saturation capacity value, 0.19 g/g, against OA vapours when compared to others, thus confirming its potential use in foldable masks for protection against chemical warfare agents.

This study was performed to investigate the effect of activated charcoal on wound healing in an experimentally induced skin wound model. Full-thickness, skin defects ($2 cm{\times}2 cm$) were made in two different areas on the back of eight New Zealand white rabbits. Eight of 16 wounds were treated with gauze-gauze-impregnated activated charocal granules, and another eight wounds were treated with gauze-soaked saline. Wound areas were measured every other day for 2 weeks after the wound-ing. Statistical analysis was performed with the student t-test. The mean percentage of wound con- traction on the 14th day in the activated charcoal-treaded group and in the saline treated group were 93.5% and 81_7%, respectively. The mean value of tensile, strength ell the 21s1 day after wounding was,42.70{\pm}0.8 kg/5cm^2$,/TEX> in the activated charcoal-treated group and $1.75 {\pm} 0.5 kg/5 cm^2$ in the saline treated group. Significantly reduced wound area (p<0.05) and high tensile strength value (P<0.O5) were observed in activated charcoal-treated group compared with those in the saline treated group. In summary activated charcoa1 significantly reduced the wound area an increased tensile strength in the rabbit 7kin wound model. These results suggest that application of activated charcoal in skill wounds will promote wound healing.

Activated charcoal(AC) is generally used in plant tissue culture. Its addition to plant tissue culture was known to many advantages and disadvantages. We investigate that sucrose hydrolysis, which by autoclaving with or without activated charcoal on different intitial pH and sucrose concentration and that the effect of activated charcoal on plant tissue culture.

This study was conducted to investigate the effect of Activated charcoal (AC) for stimulating growth and productivity of Curcuma longa Linne as affected by different concentrations of AC. Growth characteristics such as plant height and leaf length were the highest with the optimum amount of activated charcoal ranged from 10 to 30%. Root growth was elongated by the addition of 30% AC with the highest rhizome length and weight.

A protective effect of activated charcoal against the acute lead poisoning of kidney was studied in mice. Mice approximately 30 gm in weight were grouped into the control, lead acetate-treated. and the activated charcoal-treated after lead acetate groups. Lead acetate (60mg/kg) and activated charcoal (40mg/kg) were delivered orally. Serum BUN and creatine were measured and ultrastructural alteration of renal tissues were examined by electron microscopy. Activated charcoal were decreased the increase of serum BUN and Creatinine level induced by lead. Lead acetate-treated renal tissues were characterized by the loss of microvilli in the renal tubule tells, irregular nucleus, enlarged and reduced number of mitochodria, enlarged rough endoplasmic reticulum, loss of ribosomes. Cells treated with activated charcoal were similar to those of the control group. In conclusion, activated charcoal may protect the lead-induced toxicity on kidney.

A protective effect of activated charcoal against the acute lead poisoning of kidney was studied in mile. Mice approximately 30 gm in weight were grouped into the control, lead acetate-treated, and activated charcoal-treated after lead acetate groups. Lead acetate (60 mg/kg) and activated charcoal (40mg/kg) were delivered orally. Serum AST, ALT and glucose were measured and the ultrastructural alteration of liver was examined by electron microscopy. Activated charcoal decreased the increase of serum AST, ALT and glucose levels induced by lead. Lead acetate-treated hepatic cells characterized by irregular nuclei, enlarged and reduced number of mitochodria, enlarged rough endoplasmic reticulum, loss of riboscomes. Cells treated with activated charcoal were similar to those of the control group. In conclusion, activated charcoal may protect the lead-induced toxicity on liver.
