Punctuated 88% Phenol Peeling for the Treatment of Facial Photoaging: A Clinical and Histopathological Study.

BACKGROUND: Phenol peeling is considered an important agent in the treatment of facial rejuvenation; however, its use has limitations due to its high potential for side effects. OBJECTIVE: This article proposes a new peeling application technique for the treatment of photoaging, aiming to evaluate, clinically and histopathologically, the efficacy of a new way of applying 88% phenol, using a punctuated pattern. METHODS: The procedure was performed in an outpatient setting, with female patients, on static wrinkles and high flaccidity areas of the face. Accompanying photographs and skin samples were taken for histopathological analysis before and after treatment. RESULTS: It was shown that 88% phenol applied topically using a punctuated technique is effective in skin rejuvenation. CONCLUSION: The authors thus suggest, based on this new proposal, that further studies be conducted with a larger group of patients to better elucidate the action mechanisms of 88% phenol. This new form of application considerably reduced patients' withdrawal from their regular activities, besides reducing the cost, compared with the conventional procedure.

Evaluation of the anti-osteoporotic effect of Ginkgo biloba L. in Wistar rats with glucocorticoid-induced-osteoporosis by bone densitometry using dual-energy x-ray absorptiometry (DEXA) and mechanical testing.

Evaluate the effect of the extract of Ginkgo biloba in the bone alkaline phosphatase, bone mineral density, in the mechanical properties of the tibia in rats with glucocorticoid-induced-osteoporosis. After osteoporosis induction, the rats were divided into five groups: Osteoporosis; EGb1 (28 mg/Kg); EGb2 (56 mg/Kg); alendronate (0.2 mg/animal) and control. The animals were treated during 20 and 30 days. The control group was compared with the osteoporosis's (Student's t-test), while the other were analyzed by ANOVA test followed by Tukey/Dunnett'T3 (p<0.05). In the osteoporosis group the bone alkaline phosphatase, bone mineral density, the bone stiffness, the maximum load and the resilience were reduced. The bone alkaline phosphatase values increased in the EGb1 and EGb2 groups (30 days). In addition, in the EGb2 and alendronate groups (20 and 30 days) the bone mineral density increased. The extract of Ginkgo biloba restored bone alkaline phosphatase and bone mineral density using dual-energy x-ray absorptiometry.

Protective effects of Baccharis dracunculifolia leaves extract against carbon tetrachloride- and acetaminophen-induced hepatotoxicity in experimental animals.

In this work we investigated the in vivo protective effects of Baccharis dracunculifolia leaves extract (BdE) against carbon tetrachloride (CCl4)- and acetaminophen (APAP)-induced hepatotoxicity. Total phenolic content, total flavonoid content, antioxidant DPPH radical scavenging activity, and HPLC analysis were performed. Our results showed that pretreatment with BdE significantly reduced the damage caused by CCl4 and APAP on the serum markers of hepatic injury, AST, ALT, and ALP. Results were confirmed by histopathological analysis. Phytochemical analysis, performed by HPLC, showed that BdE was rich in p-coumaric acid derivatives, caffeoylquinic acids and flavonoids. BdE also showed DPPH antioxidant activity (EC50 of 15.75±0.43 µg/mL), and high total phenolic (142.90±0.77 mg GAE/g) and flavonoid (51.47±0.60 mg RE/g) contents. This study indicated that B. dracunculifolia leaves extract has relevant in vivo hepatoprotective properties.

Copaiba oil suppresses inflammatory cytokines in splenocytes of C57Bl/6 mice induced with experimental autoimmune encephalomyelitis (EAE).

Experimental autoimmune encephalomyelitis (EAE) is a murine autoimmune disease used to study multiple sclerosis. We have investigated the immunomodulatory effects of copaiba oil (100, 50 and 25 µg/mL) on NO, H2O2, TNF-α, IFN-γ and IL-17 production in cultured cells from EAE-mice. Copaiba oil (100 µg/mL) inhibited H2O2, NO, IFN-γ TNF-α and IL-17 production spontaneously or after ConA and MOG35-55 stimulation. It is suggested that copaiba oil acts on the mechanism of development of EAE by IFN-γ, IL-17 and TNF-α inhibition, modulating the immune response on both Th1 and Th17 cells.

Prophylaxis of Upper Airway Infections in a Patient with Partial IgA Deficiency: Concurrent Use of Sublingual Immunotherapy with Inactivated Whole-Cell Bacterial Extract and Der p1.

Selective IgA deficiency is the most common type of primary immunodeficiency, but there is not yet a specific effective treatment. The most prevalent clinical manifestations are infectious diseases of the respiratory system. We report herein the case of an 11-year-old female with selective IgA deficiency and recurring episodes of respiratory infections associated with rhinitis and asthma. We evaluated the efficacy of sublingual immunotherapy combined with inactivated whole-cell bacterial extract and Der p1-specific immunotherapy. After 18 months of clinical follow-up, we observed a significant reduction in the number of episodes of respiratory infections associated with control of atopic diseases. We also observed a 3-fold increase in serum IgA levels compared to treatment initiation. This case demonstrates the potential utility of the concurrent use of sublingual immunotherapy with inactivated whole-cell bacterial extract and Der p1 for successful control of allergy and infection in partial selective IgA deficiency.

Copaiba oil suppresses inflammation in asthmatic lungs of BALB/c mice induced with ovalbumin.

Asthma is a chronic inflammatory disease that represents high hospitalizations and deaths in world. Copaiba oil (CO) is popularly used for relieving asthma symptoms and has already been shown to be effective in many inflammation models. This study aimed to investigate the immunomodulatory relationship of CO in ovalbumin (OVA)-induced allergic asthma. The composition of CO sample analyzed by GC and GC-MS and the toxicity test was performed in mice at doses of 50 or 100 mg/kg (by gavage). After, the experimental model of allergic asthma was induced with OVA and mice were orally treated with CO in two pre-established doses. The inflammatory infiltrate was evaluated in bronchoalveolar lavage fluid (BALF), while cytokines (IL-4, IL-5, IL-17, IFN-γ, TNF-α), IgE antibody and nitric oxide (NO) production was evaluated in BALF and lung homogenate (LH) of mice, together with the histology and histomorphometry of the lung tissue. CO significantly attenuated the number of inflammatory cells in BALF, suppressing NO production and reducing the response mediated by TH2 and TH17 (T helper) cells in both BALF and LH. Histopathological and histomorphometric analysis confirmed that CO significantly reduced the numbers of inflammatory infiltrate in the lung tissue, including in the parenchyma area. Our results indicate that CO has an effective in vivo antiasthmatic effect.

ß-Caryophyllene ameliorates the development of experimental autoimmune encephalomyelitis in C57BL/6 mice.

Multiple sclerosis is the most common autoimmune inflammatory and demyelinating disease of the central nervous system. The experimental autoimmune encephalomyelitis (EAE) is an appropriate and a well-establish model for studying the pathogenesis of MS. ß-caryophyllene (BCP), a natural sesquiterpene found in many plant species, is a potent anti-inflammatory compound. Herein we investigated the in vitro and in vivo immunomodulatory effects of BCP on C57BL/6 mice induced with EAE. BCP was in vitro evaluated (4, 20, and 40µM) on splenocytes obtained from EAE-induced C57BL/6 mice, and in vivo (25 or 50mg/kg/day) orally administered on EAE-mice. The clinical course, body weight, cytokines and oxygen radicals production were investigated in C57BL/6 EAE-mice. In vitro and in vivo immunological responses were evaluated by ELISA, and CNS sections were stained by hematoxylin and eosin methods The in vitro production of H2O2, NO, IFN-γ, and TNF- α was inhibited by BCP (20 and 40µM) in cultured cells from EAE-mice. BCP (25 and 50mg/kg/day) reduced clinical score and severity of EAE and inhibited H2O2, NO, TNF-α, IFN-γ and, IL-17 production. EAE-mice, orally treated with BCP (mainly at 50mg/kg/day), displayed levels of cytokines and clinical signs similar to animals with no EAE disease, demonstrating the therapeutic action of BCP on EAE animals. Histopathological and histomorphometric analysis confirmed that BCP treatment significantly reduced the numbers of inflammatory infiltrates and attenuated neurological damages in the CNS of EAE-mice.
