Effect of propofol on salivary secretion from the submandibular, sublingual, and labial glands during intravenous sedation

Keisuke Masuda,Akira Furuyama,Kenji Ohsuga,Shota Abe,Hiroyoshi Kawaai The Korean Dental Society of Anesthsiology 2023 Journal of Dental Anesthesia and Pain Medicine Vol.23 No.3

Background: Recent animal studies have suggested the role of GABA type A (GABA-_A) receptors in salivation, showing that GABA-_A receptor agonists inhibit salivary secretion. This study aimed to evaluate the effects of propofol (a GABA-_A agonist) on salivary secretions from the submandibular, sublingual, and labial glands during intravenous sedation in healthy volunteers. Methods: Twenty healthy male volunteers participated in the study. They received a loading dose of propofol 6 mg/kg/h for 10 min, followed by 3 mg/kg/h for 15 min. Salivary flow rates in the submandibular, sublingual, and labial glands were measured before, during, and after propofol infusion, and amylase activity was measured in the saliva from the submandibular and sublingual glands. Results: We found that the salivary flow rates in the submandibular, sublingual, and labial glands significantly decreased during intravenous sedation with propofol (P < 0.01). Similarly, amylase activity in the saliva from the submandibular and sublingual glands was significantly decreased (P < 0.01). Conclusion: It can be concluded that intravenous sedation with propofol decreases salivary secretion in the submandibular, sublingual, and labial glands via the GABA-_A receptor. These results may be useful for dental treatment when desalivation is necessary.

Consensus Recommendations for Optimal Augmentation of the Asian Face with Hyaluronic Acid and Calcium Hydroxylapatite Fillers

Rho, Nark-Kyoung,Chang, Yao-Yuan,Chao, Yates Yen-Yu,Furuyama, Nobutaka,Huang, Peter Y. C.,Kerscher, Martina,Kim, Hee-Jin,Park, Je-Young,Peng, Hsien Li Peter,Rummaneethorn, Paisal,Rzany, Berthold,Sunda American Society of Plastic Surgeons 2015 Plastic and reconstructive surgery Vol.136 No.5

BACKGROUND:: Although the use of filling agents for soft-tissue augmentation has increased worldwide, most consensus statements do not distinguish between ethnic populations. There are, however, significant differences between Caucasian and Asian faces, reflecting not only cultural disparities, but also distinctive treatment goals. Unlike aesthetic patients in the West, who usually seek to improve the signs of aging, Asian patients are younger and request a broader range of indications. METHODS:: Members of the Asia-Pacific Consensus group—comprising specialists from the fields of dermatology, plastic surgery, anatomy, and clinical epidemiology—convened to develop consensus recommendations for Asians based on their own experience using cohesive polydensified matrix, hyaluronic acid, and calcium hydroxylapatite fillers. RESULTS:: The Asian face demonstrates differences in facial structure and cosmetic ideals. Improving the forward projection of the “T zone” (i.e., forehead, nose, cheeks, and chin) forms the basis of a safe and effective panfacial approach to the Asian face. Successful augmentation may be achieved with both (1) high- and low-viscosity cohesive polydensified matrix/hyaluronic acid and (2) calcium hydroxylapatite for most indications, although some constraints apply. CONCLUSION:: The Asia-Pacific Consensus recommendations are the first developed specifically for the use of fillers in Asian populations. CLINCIAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, V.

Tuning with Phosphorylcholine Grafts Improves the Physicochemical Properties of PLL/pDNA Nanoparticles at Neutral pH

Juliana Semensato,Júlio Cesar Fernandes,Mohamed Benderdour,Vera Aparecida de Oliveira Tiera,Aline Margarete Furuyama Lima,Marcio José Tiera 한국고분자학회 2020 Macromolecular Research Vol.28 No.2

The improvement of biological properties of polycations is a fundamental step to overcome their limitations as non-viral gene carriers. This work studied the effect of phosphorylcholine (PC) groups on the physicochemical properties of poly(L-lysine) (PLL)/pDNA nanoparticles. Phosphorylcholine-grafted PLL derivatives (PLL-PC) containing increasing proportions of PC were obtained by the reductive amination reaction with phosphoryl glyceraldehyde and characterized by 1H NMR, FTIR, and GPC measurements. The PLL-PC derivatives were used to prepare polyplexes with pDNA and their properties were evaluated by fluorescence, gel electrophoresis and dynamic light scattering (DLS) measurements. The PLL-PC derivatives were able to interact with pDNA at low N/P ratios in physiological pH to form stable polyplexes having lower zeta potentials, as evidenced by the gel electrophoresis and zeta potentials measurements. A degree of grafting of 10% increased the in vitro transfection efficiency of PLL and a degree of 20 mol% of PC groups provided colloidal stability in physiological saline solution at neutral pH. Overall, the PC-PLL derivatives exhibited improved physicochemical properties and have significant potential for further studies as non-viral gene transfer agents.
