Purpose This study was designed to verify the effect of aromatherapy on a postpartum mother's perineal healing. Method The research design was a clinical trial. The methods of aromatherapy were applied sitz bath or soap application using essential oils with Lavender, Myrrh, Neroli, Rose, Grapefruit, Mandarin, Orange, and Roman Chamomile. The subjects of this experiment were postpartum mothers who delivered vaginally with an episiotomy. They were allocated to one of three groups; the aroma-sitz bath group, aroma-soap application group or control group. To evaluate the effect of aromatherapy, the perineal healing status was measured using the REEDA scale and smears of episiotomy wound were obtained. The data were analyzed by repeated measures of ANOVA, ANCOV A, x$^2$- test, and multiple response analysis via SPSS program. Results The REEDA scale was significantly low in the experimental group at postpartum 5th and 7th days (P=.009, P=.003), respectively. Most were observed ‘few’(5-10 bacteria per field) bacteria in the smears of episiotomy wound. The one bacteria was identified in the 50.8% of subjects in pretest and two bacteria in the 60.3% in posttest. Most frequently identified bacteria were Escherichia coli and Enterococcus faecalis. Conclusion In conclusion, these findings indicate that postpartum aromatherapy for perineal care could be effective in healing the perineum perineal care could be effective in healing the perineum.

There are two groups of significant functional constituents in sesame seeds on the whole; one is the vegetable oils and another is the anti-oxidative compounds. However, although high amounts of major fatty acids are synthesized in sesame seeds, their composition is unfavorable because the contents of alpha- and gamma-linolenic acid, the essential fatty acids, are very low or do not produced in sesame seeds. So, to increase these fatty acids in sesame seeds, one strategy is to overexpress their genes, ${\omega}$-3 fatty acid desaturase for alpha-linolenic acid and delta-6 fatty acid desaturase for gamma-linolenid acid, in them. Another molecular target is to enhance alpha-tocopherol, vitamin E, because its content is very low in sesame seeds. The enzyme, gamma-tocopherol methyltransferase, catalyzes the conversion of gamma-tocophero to alpha-tocopherol. Overexpression of this enzyme in sesame seeds could be also a good molecular breeding target. Reduction of phytic acid is also another molecular target in sesame seeds because phosphorus pollution may be caused by its high content in sesame seeds. Accordingly, to do so, one of target enzymes could be myo-inositol 1-phosphate synthase which is a key regulatory enzyme in the pathway of phytic aicd biosyntheses. In this lecture, a molecular strategy for development of value-added sesame crop is described in association with some results of our experiments involved in the molecular characterizations of the genes mentioned above.

The biotransformation of monoterpenic agro-industrial wastes (turpentine oil and essential orange oil) was studied. More than 40 fungal strains were isolated from Brazilian tropical fruits and eucalyptus trees and screened for biotransformation of the waste substrates. Solid phase microextraction was used to monitor the presence of volatile compounds in the headspaces of sporulated surface cultures. The selected strains were submitted to submerged liquid culture. The biotransformation of R-(+)-limonene and ${\alpha},\;{\beta}-$ pinenes from the oils resulted in ${\alpha}-terpineol$ and perillyl alcohol, and verbenol and verbenone, respectively, as the main products. The selected strains were also placed in contact with ${\alpha}-$ and ${\beta}-$ pinenes standards. It was confirmed that verbenol, verbenone, and ${\alpha}-terpineol$ were biotransformation products from the terpenes. A concentration of 90 mg/L of verbenone was achieved by Penicillium sp. 2360 after 3 days of biotransformation.

Menthol (M) is a cyclic monoterpenode and is a major component of essential oils. Menthol, along with menthol, isomenton, etc., gives taste and odor of the mint plant, and when it comes to menthol in general, L- or (-) -menthol is usually used. Included in pharmaceuticals, cosmetics and pesticides. It has antimicrobial, antibacterial, antioxidant properties. It is also known that the licorice plant (Glycyrrhiza Glabra L.) differs from other types of plants by its medicinal properties. For many years it has been used in folk medicine. Extraction of licorice root revealed up to 25% glycyrrhizinic acid (GA). Its aglycone - glycyrrhizic acid is notable for its structural similarity to the adrenal cortex hormones. Currently, GA and glycyrrhizic acid are widely used in medicine as a remedy for colds, allergies, viral diseases, tumors. The biological activity of menthol and GA-based supramolecular compounds has been poorly studied, and their effect on the functional parameters of rat liver mitochondria has been studied little. For this purpose, in our experiments, the effect of menthol (M), glycyrrhizinic acid (GA) and their supramolecular complexes obtained in different proportions on in vitro and in vivo studies on rat liver mitochondria was studied.

The hot water extract from cinnamon (Cinnamomum cassia Presl) inhibited the activity of alcohol dehydrogenase (ADH) with IC₅₀ value of 45.6 ㎍/mL. The ADH inhibitory components in cinnamon extract were relatively stable to acid and heat, but were found to be volatile. The optimum temperature and time for extracting the ADH inhibitory components from cinnamon were 80 ℃ and 2 h, respectively. Among the essential oils of cinnamon, cinnamaldehyde was the main substance for ADH inhibition. Cinnamaldehyde is considered a competitive inhibitor of ethanol to ADH. Therefore, the cinnamon extract and cinnamaldehyde showed the potential to be used as natural materials for relieving symptoms of a hangover.

This study aimed to investigate the anti-stress function of Aucklandiae Radix (AR) and Cyperi Rhizoma (CR). The essential oils used in the experiment were extracted from AR and CR using Steam Distillation Extraction and Super critical CO₂ extraction. To observe the effects of sample administration, we measured feed intake, leukocytes, red blood cells, hemoglobin, platelets, serum serotonin content, immobility time, climbing time, and swimming time in mice subjected to chronic restraint stress as behavioral changes. The average body weight of all experimental groups increased than the average body weight of the control group. The immobility and climbing times of experimental groups A and B administered with supercritical extraction samples were shorter than those of the other experimental groups and the control group, and the swimming time was longer. The serotonin content in the blood of all experimental groups decreased compared to the normal group, and the serotonin content of the control group was increased. The authors suggest that Korean herbal medicines AR and CR may be utilized as anti-stress flavoring agents based on the above results.
