Abstract

Aim: Fifty fluids sample of abusers were examined for the presence of alkaloid abuse drugs in body liquids. Abuse drugs of liquid samples directly confirmed with rapid strip tests and their extracts were detected by quality and quantity TLC- UV methods.All of the study population were male and their age range were (Mean ±SD) = (41±22). 

Methods: Samples were daily collected from abusers of Tabriz/Iran. Urine and Saliva extracts were prepared by using LPE method. The LPE were made and shacked by 9% saline solution and organic solvents of methanol and pure ethanol and cholorophorm and ammoniac with base productive of Merck company for every 10ml of liquid samples. Then after centrifugation under concentrated section of tubes were extracted. After separation to dryness with heater, the residue was dissolved in organic solvent of methanol to reach 20 to 50-fold concentration. For TLC-UV process, the extraction residues were provided to spotting on TLC plates for doing of thin layer chromatography. So, the detection limit of different abuse drugs standards was between 300-750 ng/ml. 

Results: The quantity amount data analyzed by SPSS and IMAGEJ software’s. The result of this study has shown that above 94 percent of liquid samples from abusers in welfare organization of Tabriz /Iran were contained alkaloid abuse drugs and above 25 percent of these samples have shown drug interaction. Algorithm of constant Retention Factor parameter (RF) were comparisoned to all standards and abuse drugs. 

Conclusion: This study describes importance of liquid phase extraction (LPE) and drug testing such as TLC analysis in comparison of other rapid tests.

Introduction

Nowadays abuse drugs are globally problems that make one of the most side effects to public health. So, the selection of achievement methods to therapeutic drug monitoring (TDM) are requirement. The recovery related policy and guidelines issues not enough about the nature and distribution of all abuse drugs in the world. The perfected data to prevention and treatment of abuse disease are necessary, depend on different regional and globalization. The geographic local of some countries makes easy transit of opium compounds to the other west countries. Possibility of clinical positions to diagnostic and treatment of addiction are different in Middle east countries such as Iran. So, this study routinely refers to abuse drugs diagnosis in fluid samples such as urine and saliva. All abuse drugs and their metabolites are detectable in liquid samples. Then we have done rapid tests and confirmed of them by TLC method. Moreover, some of abuse drugs might be distinguished in these studies such Diacetyl morphine, Ethyl morphine, Hydromorphoine, Apomorphine, Morphine, Cannabis, Methadone, Tramadol, Buprexin, Amphetamine, Methamphe-tamine, Methylene Dioxy methamphetamine, Cocaine, Phencyclidine, Benzodiazepine, Three cyclic antidepressant, Phenobarbital and etc.., through this method.  So, this epidemiological study supported by the clinical laboratory of welfare organization and Hygiene center. The quantities data related on detection not enough about the nature of all kinds abuse drugs in the world. These methods are extremely helpful in quick diagnosis of abuse compounds. So, several studies including screening and confirmation of abuse drugs by thin layer chromatography have done by TLC-UV system in forensic laboratories. So, this study exactly shows quality and quantity importance of thin layer chromatography for detection of drugs and abuse drugs by application of ImageJ software. With this background this study carried out TDM (Therapeutic Drug Monitoring) with TLC-UV system at toxicology laboratories of welfare organization and hygiene center in Tabriz/Iran [1-7].

Materials and Methods

Samples providing

2ml of every sample reached to 5ml with saline solution and one droplet of ammoniac to providing liquid phase extraction process (LPE). First some of samples were directly examined for presence or absence of some drugs and abuse compounds such morphine, amphetamine, methamphetamine by rapid strip tests. Each addicted subject was asked to give a fresh sample of his saliva and urine to the laboratory before recovery. All study population filled satisfy form to participating in study. Besides providing samples, agreed to complete a questionnaire focusing on their conditions and abuser history and life style conditions characteristics. All of participants were male mean aged were 41±22 years. All of them were smokers too. The study was submitted and approved by the local ethical committee. All gave their informed consent prior to them in the study. All liquid samples were daily collected from abusers and stored in refrigerator, then pH of samples changed to alkaline condition with adding one ammoniac droplet. The pH regulated with pH paper for each sample. Extraction tubes were provided with 1 ml pure 96% Merck company ethanol and 2ml of cholorophorm and 2ml methanol and 5ml of samples.

Rapid Tests

First, all liquid samples were examined with rapid strip tests then all urine and saliva extracts were examined with TLC method. However, the results of saliva and urine strip tests were positive before recovery.

LPE and TLC-UV process

All samples were daily collected from abusers of Tabriz/Iran. Urine and Saliva extracts were prepared by using LPE method. The LPE were made and shacked by 9% saline solution and organic solvents of methanol and pure ethanol and cholorophorm and ammoniac with base production of Merck company for 5ml of liquid samples. Then after centrifugation under concentrated section of tubes were extracted. After separation to dryness with heater, the residue was dissolved in organic solvent of methanol to reach 20 to 50-fold concentration. For TLC-UV process, the extraction residues were provided to spotting on TLC plates for doing of thin layer chromatography. So the detection limit of different abuse drugs standards was between 300-750 ng/ml. After the TLC process for confirming of spots tests for the all alkaloids were comparisoned with standards spots and were visualized by UV cabinet. [3-18]. In first step of this study all samples with adding one droplet ammoniac were directly done with rapid tests then confirmed with TLC- UV methods. After doing of TLC, quantity of abuse drugs by area under the curve (AUC) and IMAGEJ software were determined. 

Results

AUC graphs and data of this study were analyzed by IMAGEJ software. According to results of this study Table1: Shows number of drugs and abuse drugs consumption lists between the study group before recovery.

Table2: Shows some of morphine TLC tests and standard quantities in before and after recovery. Table3: Shows some of amethamphetamine TLC test and standard quantities in before and recovery. Table4: Shows some of methamphetamine TLC test and standard quantities in before and recovery. Table5: Shows some of TLC test results that have shown drug interaction after recovery. Figure1 and Figure2 and Figure3 show AUC quantity of amphetamine and methamphetamine and morphine standards. Also, Figure4 shows AUC quantity of morphine TLC test in one patient. Image1.shows TLC plate with content negative results of amphetamine and methamphetamine in one recovered patient. Also, this plate shows that the RFof amphetamine(left) is more than the RFof methamphetamine(right)standard spots. Image2. shows TLC plate with content positive results of morphine(left) and morphine and codeine standard (right) in one unrecovered patient. Also, this plate shows that the RFof codeine (up right) is more than the RFof morphine (down right) standard spots. The RF (Retention Factor) is constant parameter for every drug in thin layer chromatography tests. The RF value indicates the relative distance one substance travels compared to the solvent. Hereby a ratio calculated in TLC representing the distance travelled by a component divided by the total distance travelled by the solvent. All calculation data was performed using SPSS and IMAGEJ softwares. The data were analyzed by using of variance (ANOVA ONE WAY) by post hoc comparison between groups were examined with student Newman kelus test and t-test. Differences in which p<0.05 were considered statistically significant. The results of this study show that above 94 percent of liquid samples from opioids abusers in Tabriz /Iran were contained alkaloid substances. however, drug interaction was happened in above 25 percent of these samples. [1-20].

Discussion

Opioid abusers take opioid drugs on street. They refer for their recovery to welfare organizations clinics. All drug abuse kits were provided for TLC analysis from some of special internal and external companies. Then according to these methods all samples were examined. All liquid samples were daily collected and examined from abusers in Tabriz/Iran duration since 2010, and it will have continued [1-10]. All data were obtained from laboratory and analyzed with softwares. other Data confounding factors were such as maintained medication of them with methadone, sublingual 0.2mg buprexin. Also other medications with narkan, naltrexone, Apatel, cimetidine, omeprazole, dextromethorphan and theophylline syrup, adult cold, , NSAIDs, natrium voltaren, doxepin, antihistamine deconjuant, Amoxapine, MAOs, SSRIs amitriptyline, imipramine, fluoxetine, Benzodiazepines, atenolol, Barbiturates, pantazosine, ranitidine, difenoxilate, spironolactone, caffeine, phenilbutazone and tobacco smoking, etc... were considered and recorded. and other small drug interaction factors were also recorded. So, some of these medication consumptions might be led to drug interactions. Overall liquid samples were daily collected. All of the patients had been considered history of smoking, alcohol, pain relief and sedative medications and other medication. All abusers had long history of using abuse drugs for more than three years. Not only all results of rapid strip tests for drug abusers before recovery were positive but also all liquid samples extracts were tested and confirmed with TLC-UV method. Because abusers take these maintained medications under their physicians’ orders, so their drug Interactions must be explained. However, this study procedure showed that a thin-layer chromatography for the importance to samples content of codeine and morphine and amphetamine and methamphetamine. This study also approved that Therapeutic Drug Monitoring process for TLC-UV system by softwares. This study also shows the importance of quality and quantity of thin layer chromatography for detection of drugs and abuse drugs by application of ImageJ software. For resolving drug interaction, new liquid samples have collected and tests repeated. The brand rapid tests commercially are available. The rapid strip tests have less specificity and show of false positives or false negatives results. This study focused on identifying of the multiple compounds (morphine, codeine and their synthetic analogues and other motivates abuse drugs) in liquid samples. The main goal of this study is the taken of precision results from clinical laboratory methods. Then these results will help physicians in all steps before and after recovery. [10-30] 

Conclusion

This study describes the importance of TLC analysis method. Abuse drugs of liquid samples directly confirmed with rapid strip tests and their extracts were detected by TLC- UV methods. This study shows quality and quantity importance of thin layer chromatography for detection of drugs and abuse drugs by application of ImageJ. This study also showed that therapeutic drug monitoring process with TLC-UV system at laboratories of welfare organization and hygiene center in Tabriz/Iran.
