COMPARISON OF HEPATOPROTECTIVE ACTIVITY OF NISHA LAUHA (NL) AND NISHA LAUHA WITHOUT LAUHA BHASMA (NLWL) AGAINST CCL4 INDUCED HEPATOTOXICITY IN WISTAR RATS

Introduction: Many herbal drugs are used to treat liver diseases, but the dose of the herbal drug is high, and they have lesser palatability. An ideal medicine is a medicine that is effective, easy palatable and produces quick action in a low dose. It is possible by adding metals like Lauha (Iron) to the herbal drugs. Objective: To compare the hepatoprotective effect of Nisha Lauha (NL) and Nisha Lauha without Lauha Bhasma (NLWL) in experimental rats. Materials and methods: 40 rats were taken divided into five groups, and each group contained eight rats. Among these groups, four groups receive 0.2 ml of injection containing the 0.1 ml CCL4 plus 0.1 ml liquid paraffin given intraperitoneally for 28 days to induce Hepatotoxicity. Both Test groups received NL and NLWL at a dose of 45mg/kg bd. wt. and 450mg/kg bd. wt. respectively for 28 days. The standard group receives silymarin at a 100 mg/kg bd dose. wt. for 28 days by oral route. The hepatoprotective effect was analyzed using biochemical parameters and histopathological study of the liver. Results: Both the Test and standard groups do not show toxic effects against CCL4 induced hepatotoxicity and lower the dose of the herbal drug due to the addition of Lauha. Conclusion: The result suggests that both test group NL and NL without Lauha Bhasma shows the hepatoprotective activity as equivalent to standard drug silymarin. The addition of Lauha Bhasma to herbal drugs decreases the dose without affecting the drug’s efficacy against the hepatoprotective effect.

Gallic Acid-Containing Gelatin-Based Nonwoven Mat with Synergistic Photodegradation and Photoindication Function for Reducing Nicotine

Cigarette smoking is a popular habit that has negative health consequences for populations. In this study, we developed a gallic acid-containing, gelatin-based nonwoven mat with photodegradation and photoindication functions. This could react with sidestream cigarette smoke and simultaneously inhibit the activity of the microbe growth in the air. The results of a fluorescence emission spectrum evidenced this photoindication function. Neither the nicotine nor gallic acid showed a redshift emission spectrum. However, the emission spectrum of the nonwoven mat exhibited the redshift and increased in intensity after absorbing the sidestream cigarette smoke. In this spectral evidence, the natural polymer played a key role in the photoindication function’s display because it could dissolve the nicotine of the sidestream cigarette smoke and cause it to react with the gelatin structure. The high performance liquid chromatography–mass spectroscopy results indicated that the gallic acid and ultraviolet (UV) light enhanced the absorption of nicotine and nicotine-like derivatives, which were dissolved by the Tween 80 of nonwoven mat. The liquid paraffin and Tween 80 could oxidize, dehydrogenate, and demethylate the nicotine that was absorbed by the gelatin nonwoven mat. In conclusion, the nonwoven mat developed in this study provided the functions to filter the nicotine of sidestream smoke and activate the photoindication property by absorbing 365-nm UV light.

Formulation and Development of Aceclofenac loaded Microsponges Topical Drug Delivery System using quality by Design Approach

The proposed study is focussed at developing Aceclofenacmicrosponges for topic drug delivery systems. QbD was applied for better understanding of the process and to generate design space, using quality target product profile, critical quality attributes, and risk assessment. The aim of the experiment was to prepare a safe, efficacious, stable and patient compliant microsponge dosage form of Aceclofenac. Materials and methods: Pre-formulation studies were carried out which helped in developing an accurate dosage form. UV, FTIR, DSC, and SEM studies were done for pre-formulation and post-formulation evaluations. These study deals with the design and optimization of Aceclofenacmicrosponges loaded topical drug delivery system to the controlled release of active drug into the skin in order to minimize the systemic exposure and minimize local cutaneous reactions to active drugs by DoE method of QbD Approach. AceclofenacMicrosponges were prepared by quasi emulsion solvent diffusion method using Eudragit-RS100 as a polymer, polyvinyl alcohol, Ethanol as Internal phase volume and Liquid paraffin as External phase volume. In this study, we found that the controlled release of aceclofenac microsponges.

Conversion of Residual Palm Oil into Green Diesel and Biokerosene Fuels under Sub- and Supercritical Conditions Employing Raney Nickel as Catalyst

A comprehensive study of the thermal deoxygenation of palm residue under sub- and supercritical water conditions using Raney nickel as a heterogeneous catalyst is presented in this paper. Hydrothermal technology was chosen to replace the need for hydrogen as a reactant, as happens, for example, in catalytic hydrotreatment. Several experiments were carried out at different reaction temperatures (350, 370, and 390 °C) and were analyzed with different times of reaction (1, 3.5, and 6 h) and catalyst loads (5, 7.5, 10 wt.%). No hydrogen was introduced in the reactions, but it was produced in situ. The results showed the selectivity of biokerosene ranged from 2% to 67%, and the selectivity of diesel ranged from 5% to 98%. The best result was achieved for 390 °C, 10 wt.% catalyst load, and 3.5 h of reaction, when the selectivities equal to 67% for biokerosene and 98% for diesel were obtained. The Raney nickel catalyst demonstrated a tendency to promote the decarboxylation reaction and/or decarbonylation reaction over the hydrodeoxygenation reaction. Moreover, the fatty acid and glycerol reforming reaction and the water−gas shift reaction were the main reactions for the in situ H2 generation. This study demonstrated that a hydrothermal catalytic process is a promising approach for producing liquid paraffin (C11−C17) from palm residue under the conditions of no H2 supply.

Autoinflammatory/Autoimmunity Syndrome Induced By Adjuvants (ASIA) Due to Silicone Incompatibility Syndrome

The adjuvant-induced autoimmune syndrome (ASIA) is associated with a dysregulation of the innate and adaptive immune system after exposure to chemical compounds, including liquid paraffin, silicone gel, acrylamides, and hyaluronic acid. Due the increase of the use of these compounds in cosmetic procedures, the prevalence of this syndrome is increasing. We present the first report in Ecuador associated to ASIA after an elective silicone breast prosthesis procedure, manifested as polyarthralgia, positive antinuclear antibody, anticentromere antibody, and a moderate positive Sclero-70.

Effect of Bivalent Vaccines against Vibrio anguillarum and Aeromonas salmonicida subspecie achromogenes on Health and Survival of Turbot

The efficacy of intraperitoneal injection of an oil-based bivalent autogenous vaccine and the commercial vaccine AlphaJect 3000 (Pharmaq AS) to prevent atypical furunculosis and vibriosis in turbot was analyzed. The effect of both vaccines on health parameters and survival of fish after challenge with V. anguillarum and A. salmonicida subsp. achromogenes was tested. The autogenous vaccine conferred high levels of protection and long-lasting immunity against both pathogens with a single dose. However, severe side effects were observed in turbot injected with this autovaccine and minor negative effects with the AlphaJect 3000 vaccine and the adjuvant Montanide or Eolane. All vaccinated fish showed remarkable antibody agglutination titers, higher than those of control fish, which were maintained 160 d after vaccination. In conclusion, the autogenous bivalent vaccine induces long-lasting protection against atypical furunculosis and vibriosis in turbot, after administration of a single dose, at the cost of high side effects in fish. Therefore, the development of new vaccines should focus on autovaccines and the use of liquid paraffin adjuvants that increase protection with reduced or no side effects.

Numerical Simulation of Paraffin Melting Process in an Inclined Channel

Numerical simulation of the melting of paraffin in the inclined straight channel shows that the melting speed of paraffin is faster in the early stage and gradually slows down in the later stage. It is found that heat conduction is the main heat transfer mode in the early stage of paraffin melting. With the increasing number of liquid paraffin, natural convection occurs in the liquid paraffin. The liquid paraffin with higher temperature flows upward due to the effect of buoyance and lift, and convection heat transfer gradually increases and takes the dominant position in the melting process.
